Heritage Hills holds some of Oklahoma City's oldest and largest homes, many built in the first decades of the twentieth century. Their plaster walls, hardwood floors, basements and aging plumbing respond to water damage differently from newer houses, and exterior repairs fall under the city's historic preservation rules. This page explains what owners should know.

## Key facts

- The Heritage Hills Historic and Architectural District joined the National Register in 1979 [1].
- The neighborhood is also a city historic preservation district, so exterior work first needs a Certificate of Appropriateness [2].
- The Overholser Mansion, completed in 1903, is often described as Oklahoma City's first mansion [3].
- In old houses with dense plaster, starting drying within the EPA window of 24 to 48 hours matters even more [4].

## The houses of Heritage Hills

Heritage Hills sits just north of downtown Oklahoma City, roughly between NW 14th and NW 21st Streets and from Walker and Robinson Avenues west toward Classen Boulevard. Its National Register listing, made in 1979, recognizes more than 350 contributing buildings [1]. The Overholser Mansion at NW 15th Street, completed in 1903, is often called the city's first mansion and remains a landmark of the area [3].

Most houses here date from the early 1900s through the 1920s and 1930s. They range from large Prairie School, Colonial Revival, Tudor Revival, Mediterranean and Georgian homes to more modest bungalows and foursquares. Many have two or more stories, full or partial basements, attic rooms, servants' stairs, plaster walls, hardwood floors, elaborate woodwork and multiple bathrooms added or updated over the decades.

Heritage Hills is also inside an Oklahoma City historic preservation district. The neighborhood association notes that exterior changes need approval, a Certificate of Appropriateness, from the city's preservation commission before work begins [2]. That rule shapes how water damage repairs to windows, doors, roofs and porches are planned.

## Water damage patterns in Heritage Hills homes

- **Old supply lines:** Galvanized steel and early copper lines corrode and fail at joints, often inside plaster walls.
- **Basement seepage:** Older basements with stone or brick walls let water in after long rains on saturated clay soil.
- **Leaks from upstairs baths:** Bathrooms added on upper floors over decades sit above plaster ceilings and ornate rooms.
- **Roof and gutter leaks:** Complex roofs with valleys, dormers and built-in gutters leak into attics and walls during storms.
- **Radiator and boiler systems:** Some homes still have hot water or steam heat; a failed radiator valve can release water upstairs.
- **Hardwood cupping:** Original oak and pine floors absorb water quickly and cup if not dried evenly.

## Drying plaster walls and ceilings

Plaster on wood or metal lath is standard in Heritage Hills houses. It behaves very differently from drywall after a leak. Plaster is dense and absorbs water more slowly, so it often survives a short leak without needing removal. It also releases water slowly, which means it takes longer to dry and needs steady dehumidification rather than a quick blast of air.

The risk with wet plaster is loss of grip. Plaster holds onto lath through keys, the bits that squeeze between the lath strips when it is applied. Water and the weight of soaked material can break those keys, especially on ceilings. A ceiling that sags, cracks in a new pattern or sounds hollow when tapped may be separating and could fall. Keep people out from under it and let the crew evaluate it.

Plaster specialists can often reattach loose plaster with adhesive and washers and patch damaged areas to match. That approach keeps original walls and moldings intact and suits the character of the house better than tearing out and replacing with drywall.

## Original hardwood floors after a leak

Many Heritage Hills homes still have their original oak or pine floors, often laid in narrow strips over plank subfloors. Water from a leak upstairs or a supply line failure can soak into the boards and subfloor, causing cupping. Because old floors have been sanded several times, the wear layer may be thinner than on newer floors, so aggressive sanding after water damage is a concern.

The best outcome comes from drying evenly and patiently, with floor drying mats or panels and steady dehumidification. Boards often settle back toward flat as they dry. Sanding too soon can leave them crowned. A flooring specialist experienced with older floors can judge whether the floor can be refinished or needs some boards replaced with matching reclaimed wood.

## Basements in Heritage Hills houses

Unlike most newer Oklahoma City homes, many Heritage Hills houses have basements, sometimes partial, holding furnaces, boilers, water heaters, laundry and storage. These basements often have walls of stone, brick or early concrete, and they can take on water from saturated soil during long rainy periods, from leaks upstairs and from sewer backups through floor drains.

Drying an older basement takes time because masonry holds water. Pumping, removing wet stored items, cleaning and running [dehumidifiers](https://waterdamageoklahomacity.com/services/structural-drying/) are typical steps. If the water came from outside or the sewer, cleaning and disinfection are needed. Equipment in the basement, such as boilers and electrical panels, should be checked by qualified technicians before use. See [flooded basement cleanup](https://waterdamageoklahomacity.com/services/flooded-basement-cleanup/) for more detail.

## Historic materials and water damage approach

| Material | Typical response to water damage |
| --- | --- |
| Plaster on lath | Dry in place where sound; reattach or patch loose areas |
| Original hardwood floors | Dry with mats and dehumidifiers; refinish once dry |
| Painted trim and millwork | Dry and clean; lead-safe practices before sanding [6] |
| Stone or brick basement walls | Pump, clean, dry; address drainage |
| Galvanized supply lines | Repair or replace failed sections; consider wider repiping |
| Radiators and boiler piping | Repair by a heating specialist; dry surrounding areas |

## Certificates of Appropriateness for repairs

Because Heritage Hills is a city historic preservation district, exterior changes generally need a Certificate of Appropriateness from the Historic Preservation Commission before work begins [2][7]. City notices show that many routine projects, such as roof work, storm windows and fences, are approved administratively by staff, while larger changes may go before the commission. A certificate typically becomes final after an appeal period.

Interior water damage work, such as drying, removing [wet drywall](https://waterdamageoklahomacity.com/guides/how-long-drywall-takes-to-dry/) or plaster, and refinishing floors, does not need historic review. Exterior repairs that follow a water loss might: replacing damaged windows, changing roofing material, altering a porch or replacing doors. Temporary measures such as tarping a roof after storm damage are typically treated as emergency protection.

Building, plumbing, electrical and mechanical permits are separate, issued by the city's Development Services Department [5]. If repairs involve both, start the historic review early so materials are approved before you need them.

## Approvals that may apply in Heritage Hills

- Certificate of Appropriateness for exterior changes from the Historic Preservation Commission or its staff [7].
- Building, plumbing, electrical and mechanical permits from Development Services [5].
- Lead-safe work practices for painted surfaces in pre-1978 homes [6].
- Asbestos testing before disturbing old pipe insulation, flooring or plaster texture.
- Neighborhood design review committees offer non-binding advice to owners [2].

## Aging plumbing in century-old houses

Most Heritage Hills houses have been replumbed at least partly, but it is common to find a mix of materials: original galvanized steel in some walls, copper in remodeled baths, newer PEX or CPVC in kitchens, and cast iron drains. Galvanized lines corrode from the inside, narrowing and eventually leaking at threaded joints. Cast iron drains crack and rust through.

When a leak occurs, the plumber may find that the failed section is part of a larger problem. Repiping a large historic house is a significant project, and it often makes sense to coordinate it with the water damage repairs while walls and floors are already open. That decision is between you and your plumber, but it is worth considering before the walls are closed.

Radiator heating systems add another source. A failed radiator valve, a leaking boiler or a burst radiator during a power outage in winter can release water upstairs. A heating specialist should repair those systems, while the restoration contractor dries the affected rooms.

## Preparing for a contractor visit in Heritage Hills

1. **Shut off the supply:** [Shut off the main](https://waterdamageoklahomacity.com/guides/what-to-do-after-a-burst-pipe/) valve or the fixture supply, and turn off power to wet areas if safe.
2. **Note the house:** Tell the contractor the approximate age of the house, whether walls are plaster and whether there is a basement.
3. **Identify heating:** Say whether the home has forced air, radiators or a boiler.
4. **Flag features:** Point out original woodwork, plaster moldings, stained glass and floors you want protected.
5. **Plan access:** Many streets have on-street parking only; mention driveways, alleys or carriage house access.
6. **Gather records:** Note any lead or asbestos testing already done and past plumbing work.

## Attic rooms and roof leaks in large old houses

The steep roofs of Heritage Hills homes often enclose large attics, some finished as bedrooms, studios or storage rooms, and many with dormers, valleys and built-in gutters. Hail and wind-driven rain are common in central Oklahoma, and these complex roofs give water many places to get in. Built-in or box gutters, hidden behind the roof edge, can overflow or rust through and send water into the walls below.

A roof leak in an old house may travel a long way before it shows up as a stain, running along rafters or down inside a wall. Moisture mapping helps trace it to the source. Wet attic insulation is usually removed. Plaster ceilings below are dried and evaluated. If the roof covering is changed during repairs, remember the historic review step for exterior materials.

## Garage apartments and carriage houses

Many Heritage Hills lots have a carriage house or garage apartment at the back, often reached from an alley. These buildings have their own plumbing, sometimes with long supply and drain lines running from the main house. In winter, lines to outbuildings are particularly prone to freezing because they run through unheated spaces or shallow ground.

If a garage apartment is rented, water damage there involves the owner and the tenant. Report and document it separately on your claim, since outbuildings may fall under a different part of the policy. Protecting those lines with insulation and keeping the space heated during freezes helps prevent a repeat.

## Antiques, rugs and family collections

Heritage Hills homes are often furnished with antiques, oriental rugs, books, art and family papers. Water damage puts all of these at risk. Wool rugs should be lifted off wet floors and sent to a rug cleaner experienced with water damage before dyes bleed. Antique furniture should be moved off wet floors and dried slowly, away from direct heat, to avoid cracking veneers and joints.

Books and papers that are wet can be frozen in sealed bags to stop mold until a conservator can treat them. Framed art that got wet should be removed from the frame by a framer or conservator. Photograph everything before it is moved for your claim, and ask the contractor how they handle high-value contents.

## Freezing weather in drafty historic houses

Older houses were built before modern insulation and air sealing, and many Heritage Hills homes still have original wood windows, uninsulated exterior walls and plumbing runs along outside walls or through unheated basements and crawl areas. During a hard freeze, those spots get cold enough to freeze pipes, especially behind kitchen sinks and in bathrooms on exterior walls.

Before cold snaps, open sink cabinets on outside walls, let a faucet drip, and keep the heat steady day and night. If you heat with a boiler or radiators, make sure the system is serviced before winter; a heating failure during a freeze can lead to both frozen supply lines and a damaged heating system. If you travel, ask someone to check the house daily or shut off and drain the water.

## Mold concerns in older homes

Older homes can be slower to dry because of dense plaster, masonry basements and limited airflow in wall cavities. That makes the first 24 to 48 hours especially important [4]. A musty smell in a basement, closet or behind built-in cabinetry after a leak is a sign that moisture remains and should be checked with a meter.

If mold appears, the affected area is contained and cleaned or removed, and the moisture source is fixed. In historic houses, the goal is to remove what must go while preserving original materials where possible: plaster can often be cleaned and treated, while wet drywall patches from past repairs may simply be replaced.

## Built-in cabinets, bookcases and pantries

Heritage Hills houses are known for built-in features: bookcases flanking fireplaces, butler's pantries, china cabinets, window seats and linen closets. Water running along floors or down walls can soak the bases of these built-ins and the space behind them, where it is hard to see and harder to dry.

Restoration crews may remove baseboards or a toe board to get air underneath, drill discreet holes in hidden areas, or use cavity drying systems. Solid wood built-ins often dry well if reached quickly; plywood or particleboard additions from later renovations may swell and need replacement. Ask the crew to photograph and label any trim they remove so it goes back in the same place.

## First steps by water source in a Heritage Hills home

| Source | First step |
| --- | --- |
| Upstairs bathroom leak | Shut the fixture or main valve; check the plaster ceiling below |
| Radiator or boiler leak | Shut the boiler and isolate the radiator; call a heating specialist |
| Basement seepage | Move stored items; pump water; check the furnace and panel |
| Roof or box gutter leak | Catch drips; arrange tarping; trace the path inside walls |
| Frozen pipe | Shut the main valve; open faucets; thaw gently |

## Insurance questions for historic homes

Water damage claims on historic homes raise questions newer houses rarely face. Matching original materials, such as plaster moldings, old-growth hardwood and wavy window glass, can be difficult, and an adjuster may propose modern substitutes. Ask early how your policy handles matching and like-kind replacement, and whether specialty trades such as plaster restorers are covered.

Code upgrades are another question. When walls are opened, current code may require changes to wiring or plumbing that the original house never had. Many policies include limited ordinance or law coverage for those upgrades. Historic review requirements can also affect which materials are acceptable for exterior repairs. Photograph original details before anything is removed; those photos support the claim and guide the craftspeople who restore them. The Oklahoma Insurance Department provides consumer help if you have trouble with a claim.

## Living in or near the house during repairs

Large historic homes can sometimes stay partly occupied during water damage repairs, with affected rooms closed off and drying equipment running. If the kitchen, the only full bathroom or the heating system is affected, or if contamination is involved, staying elsewhere is more practical. Additional living expense coverage, if your policy includes it, may help with temporary housing.

Staying close lets you meet the crew, see the daily readings and keep an eye on the house. Downtown and Midtown hotels and short-term rentals are a short distance from Heritage Hills.

## Heritage Hills water damage questions

### Can plaster walls be saved after a leak?

Often, yes. Plaster usually survives a leak if it stays attached to the lath. It is dried slowly, and loose areas can be reattached and patched to match.

### Do I need a Certificate of Appropriateness for water damage repairs?

Not for interior drying and repairs. Exterior changes, such as replacing windows, doors or roofing, generally need one. Emergency tarping is typically treated as protection.

### Why does my basement take on water after long rains?

Saturated clay soil holds water against older basement walls, which can seep through masonry joints and cracks. Drainage improvements outside often help.

### Should I repipe while the walls are open?

If your house has old galvanized lines, it is worth discussing with a plumber. Coordinating repiping with water damage repairs can avoid opening walls twice.

### Will my original floors need to be replaced?

Often not. Even drying usually lets cupped boards settle back. A specialist can judge whether refinishing is possible given the remaining wear layer.

### Who issues permits for repairs in Heritage Hills?

Oklahoma City's Development Services Department issues building and trade permits. Historic review is a separate process through the Historic Preservation Commission.

### My radiator leaked upstairs. Who do I call?

A heating specialist to repair the radiator or boiler, and a restoration contractor to dry the floor and the ceiling below. Shut the boiler off and close the radiator valve first if you can.

### Can box gutters cause water damage inside the walls?

Yes. Built-in gutters that overflow or rust through can send water into the wall cavity below the roof edge. Moisture mapping can trace it, and the gutter needs repair before the walls are closed.

### Is wet plaster a safety hazard?

It can be. A soaked plaster ceiling may lose its grip on the lath and fall. If a ceiling sags, cracks in a new pattern or sounds hollow, keep people out from under it until it is evaluated.

### Can old windows be repaired after water damage?

Usually. Wood sashes can be dried, repaired and reglazed. Replacement is an exterior change that generally needs a Certificate of Appropriateness in Heritage Hills.

### Should the basement furnace be checked after a leak?

Yes. If water reached a furnace, boiler or water heater in the basement, have a qualified technician inspect it before use. Controls and burners can be damaged by water.
