Most basements are a little bit more than a location to cultivate cobwebs and store cans of paint. However, fixing up a full-height basement can significantly increase the functional living space in your house at a far lower expense than adding on.
Although expenses vary with the size and complexity of the job, renovating an existing basement starts at about $20 per square foot, a fraction of what it costs to develop an addiction or increase the size of second-floor space with
dormers. And as we reveal here, basements can become any among a number of living locations. That discusses why home builders like Rick Heim, a Boston-area specialist, won’t even utilize the “B” word. To Heim and like-minded professionals getting on the bandwagon, a basement is a “finished lower level.”
Altering a concrete dungeon into an inviting living area is an obstacle, and not every basement is a good prospect for finishing. Secret considerations for conversion include managing wetness, adding ventilation and light, and finding a method around hanging drain lines, ductwork and electrical wiring. Although you can do some of the work yourself, most of it is best delegated to an experienced pro.

Getting It Dry
” If your home has a history of basement flooding,” says Newton, Massachusetts, redesigning contractor Paul Eldrenkamp, “you’re insane to consider a basement renovation until you resolve that issue.” Most water issues, he says, are brought on by insufficient control of roof runoff. Eldrenkamp estimates that 2 in. of rain falling on a 2,000-sq.- ft. the home produces 2,600 gals. of water. So fixing cracks in the foundation, ensuring the seamless gutters are clear of clogs and sloping the ground far from your home will resolve a lot of flooding issues. But if water still seeps in, setting up or repairing foundation drains might be the treatment.
Either of these is a big job that requires excavating around the boundary of your house. An alternative is to set up drains along interior basement walls. Contractors get rid of a strip of concrete next to the wall and dig a trench around the beyond the floor. New drain lines capture water and thrashing it to a sump where it is drained of your home or directed to gravity-fed drains if the grade permits it. Eldrenkamp says this kind of work isn’t cheap, costing $50 to $60 per foot in his area, however, it is highly efficient at keeping water out of a finished area. Masonry sealants, such as those made by Drylok or Thoroseal, likewise can be reliable in controlling moisture when applied to interior walls. However, as Heim warns, “If you have an ocean can be found in, they are not going to stop it.”
Radon, a naturally taking place radioactive gas common in some parts of the nation, is another consideration when you transform a basement. A simple test will determine the level of radon and suggest whether mitigation is a good idea. If so, radon can be gathered by buried drain lines and vented to the outside, similar to excess water.

Satisfying Building Regulations
Building codes differ, however generally the ended up ceiling height in a basement needs to be at least 7 ft. Codes allow some lower blockages– structural beams that can’t be moved, for example– and building inspectors typically want to jeopardize when contractors experience small height problems. Your best bet is to contact your regional inspector while you’re still in the planning stage. The inspector is likely to be more supportive when he gets consulted early at the same time.
When height requirements are satisfied, there is still the concern of windows and doors for emergency escape or egress. Building regulations generally need one emergency window (or door) in a basement that contains habitable space, though each bedroom requires its own. If you turn a basement into a living room or a home theater, you most likely will not require the very same number of fire escape that would be required for a number of bedrooms. Including a code-compliant fire escape can be costly in a below-grade basement. Although products are readily available for simply this scenario, the home builder might need to cut through concrete walls to create a larger opening.
Stairways likewise can be a problem. Building codes typically require a minimum of 7 3/4 in. for stair risers and 10 in. for treads. Older staircases may not fulfill these requirements and might need to be changed, contributing to the expense of the task. Some contractors suggest new staircases anyhow to make a remodeled basement more inviting. Another factor to consider: Adding a finished floor may have the unintended result of lowering the very first stair riser, producing a trip risk. Eldrenkamp states inspectors in his area will accept a lower riser on the primary step, but that’s likewise an indicate check with the building inspector’s workplace.

Handling Low-Flying Utilities
When plans call for an ended up the basement in new construction, ceiling height and utilities can be planned appropriately. Remodelers are seldom so lucky. “Normally,” states Eldren-Kamp, “people do not plumb homes with an eye to remodeling their basements.” Water lines, duct, bathroom, and kitchen area drain, and supply and return lines for a hot-water heating system all could be located below ceiling joists, where they are smack in the way of remodeling. Contractors have only a few options: Move them, box them in or leave them as they are.
Circuitry and plumbing frequently can be transferred. But the procedure is pricey, and it is sometimes next to impossible to move bulky energies like drain lines and heating ducts. As a result, contractors might hide plumbing, heating, and wiring run in a ceiling, wall or closet. Heim tries to make a finished ceiling appearance stabilized in situations where he is forced to box in energies. For instance, if he has to hide plumbing work on one side, he might develop other locations to create a coffered ceiling. The result is a pleasing detail whose real function is not apparent.
And often upsetting pipes are just left exposed and painted. “For the most part,” Eldrenkamp states, “individuals have different expectations for the basement.” One thing to remember: When tucking water and drain lines out of sight, do not obstruct access to water shutoffs and drain clean-outs.
Due to the fact that plumbing and wiring can be tough to disguise, many contractors rely on drop ceilings. Typical to the industrial structure as well as to residential construction, these ceilings include a metal structure suspended numerous inches below ceiling joists that support drop-in panels readily available in a variety of textures and colors. Acoustic panels that deaden noise are widely utilized, specifically if the basement is used as a home theater or a vacation for teenagers. Reasonably low cost and ease of setup make this ceiling an easy choice, however, some builders think they are an anesthetic turnoff. “The quickest method to make a basement appear like a basement,” says Heim, “is to put a drop ceiling in.” He is far more most likely to recommend a plaster or a drywall ceiling, much like the rest of the home.

Finished Wall and Floors
Hiding concrete or block behind brand-new walls is the easy part. Building walls that will not motivate mold and mildew, or be damaged by condensation, is a lot harder. Because concrete in contact with the ground is constantly cool, it can become a condensing surface for water vapor in the warm air getting away from an ended up basement. The result? Damp structure products, mildew and, eventually, rot. Air will be musty, finished surfaces messed up. As Massachusetts contractor Fred Unger puts it, “If you get a hack to do the work, it’s going to smell like gym socks.”
Unger, like other contractors, isolates damp concrete walls from the remainder of the area with 1 in. of extruded polystyrene insulation, followed by a layer of 6-mil polyethylene. On rough walls, foam insulation can be sprayed on. Impenetrable layers of foam and polyethylene separate wall framing from moist concrete or block while giving water vapor no cool surface area on which to condense. Other builders may avoid the polyethylene vapor barrier even if they use foam insulation.
Joe Stanton, a Rhode Island home builder, for instance, thinks it makes more sense not to build walls too tight. It’s much safer, he states, to give walls a method of drying out the need to any water or condensation collect within. Worries of trapped moisture also prompt some remodelers to utilize light-gauge steel framing on outside basement walls. Although contractors may differ on this information, they would agree that obvious water issues, such as leaking structure walls, need to be solved first.
Despite their wetness problems, below-grade surfaces typically do not require as much insulation as exterior walls built above ground. Even in winter, the temperature level of the earth listed below the frost line might be no chillier than 55 ° or 60 ° F. As a result, some contractors just skip fiberglass insulation in stud walls if they utilize rigid or sprayed-on foam.
Allure House Improvements, a Long Island, New York, redesigning business, utilizes an entirely different approach in creating finished basement walls. Its growing basement service counts on a wall-finishing system established by Owens Corning. The system uses fiberglass panels and trims pieces that snap into PVC structural framing
Wall panels are ended up in material, eliminating the requirement for drywall taping or painting. Carl Hyman, the business owner, and president states the system is up to 30 percent more pricey than standard drywall building however has a longer life span and quickly endures the wet conditions discovered in basements. Upkeep costs, he says, also are lower. Any parts of the system that end up being damp or damaged can be eliminated. Regardless of its useful benefits, the system does not look like a typical wall and might be a difficult sell esthetically in some parts of the country.
When it comes to floor covering, just about any material will work– tile, carpet, vinyl or laminate. Fewer contractors, however, choose conventional hardwood flooring due to the fact that wetness in the piece might cause the wood to swell and buckle. Remodelers need to apply a masonry sealer before setting up any finish flooring. Eldrenkamp uses a fairly intricate system of polyethylene, rigid-foam insulation, 153 sleepers, and tongue-and-groove plywood to produce a floating-floor system– that is, a flooring not directly attached to the piece. It produces a warm, dry ended up floor, however, built-up floor systems such as this may not be possible in basements with extra-low ceilings.

Lighting Lessons
Basements in houses whose lot is sloped to permit walkout basements can have abundant light. But when brightened only by small, ground-level windows, basements can be dark and uninviting. An initial step is to clear away bushes from existing window wells to take advantage of what natural light is readily available. If the basement is served by a steel bulkhead, a door with glass lights can be set up at the bottom of the actions and the bulkhead doors left open, at least in great weather conditions. Likewise, changing any solid doors in the basement stairwell with glass doors also may help to increase the quantity of natural light.
Yet these steps are hardly ever enough, and remodelers normally add several basement lighting circuits. In basements with plenty of headroom, mounted lights can be appealing, even if it utilized just as accent lighting. However when the ceiling drops to the 7-ft. range, ceiling-mounted components are most likely to be bumped or broken. Fluorescent components can be recessed into a drop ceiling, but they can provide a basement an overlit workplace appearance. As a result, contractors frequently rely on recessed incandescent lighting. “Can” lights are inconspicuous and can be fitted with either spot or flood lamps, and when put on a dimmer switch, they make lighting more flexible than other alternatives.
Lighting by itself uses relatively little electrical power, but other amenities may be power hogs. A sauna or steam room might require 40 to 50 amps, quickly maxing out primary electrical panels that are minimal, to begin with. And updating a 100-amp panel to a 200-amp panel can cost $1,000.

Ventilation Issues
Musty, wet air might be something that you can endure in a basement you check out only periodically. Once the basement ends up being a real home, some kind of ventilation is vital in controlling air quality. Eldrenkamp likes to use a reversing fan made by Vent-Axia. In the winter, it attracts fresh, dry air from outdoors (the volume of air is low enough so the basement does not feel like an unheated shed). In the summertime, damp air can be drained of your home. Hyman’s business typically utilizes a wall-mounted air exchanger made by Humidex, which vents cooler, moist air to the outside. If the house currently has a forced-air heater that consists of air-conditioning, the basement can be included as another zone. Air-conditioning naturally reduces wetness levels in the air.
Yet another alternative is to add dehumidifiers, however, there are several downsides to them. They are more pricey to run than a ventilation fan, and unless a dehumidifier is plumbed straight to a drain line it will have to be emptied occasionally. And, as Heim explains, dehumidifiers tend to be loud.
Fresh air is just as essential to boilers, furnaces and gas-fired water heaters as it is to people. These gadgets often are confined in a small mechanical closet. But in doing so, contractors will need to add a source of fresh combustion air. Go into once again the code-enforcement officer: It’s an excellent concept for you to check regional code requirements for offering combustion air for those devices.
There’s a lot to think of when transforming a basement into a bright, welcoming living area. Once the work is done, you’ll never wish to leave.

Dressing Up a Window
It’s difficult to enjoy the view when all you can see is a curtain of corrugated steel, but that’s precisely what you’ll get in an average basement window well. Changing that dreary landscapes may be easier than you believe.
For about $130, you can include a view of the seaside, mountains, forests, desert or golf course. Scenic Window Wells’ WELLliner is a weather-resistant polystyrene liner that slips into a standard window well. When you look out the basement window, you may imagine yourself in any among 36 postcard-perfect locales. Liners are offered in two sizes, and the versatile sheets can be cut to fit. A light package also is readily available to keep the scene noticeable when the sun goes down.
If all you desire is extra light, check out the MaxLight2 System ($ 120 to $160), which promises to increase the amount of sunlight in the basement by as much as 10 times. It consists of a versatile well liner that fits inside an existing window well and a reflection panel that is attached to the side of your house. Sunshine striking the reflection panel is bounced onto the good liner and after that into the basement.
Bilco’s ScapeWEL supplies light along with a fire escape from the basement. The high-density-polyethylene window well snaps together and sits in an enlarged well. Its two- or three-tiered design develops racks that can be utilized for plants– or as steps throughout an emergency exit from the basement. Readily available in a number of sizes, the 48- to
