Hidden Details of Basement Refinishing
Thursday, March 24th, 2011The quickest way to gain more usable square footage in your home is to finish the basement. The lower level is also where you can create spaces you’ve always longed for like an exercise room, home theater or wine cellar.
Because it’s ripe with so many possibilities, finishing a basement is one of the most popular Do-It-Yourself remodeling projects. But this type of project can also set many traps for missteps and future disasters if the job is not done properly. Here are some important points to consider before finishing a basement:
Building Permit
To assure that the work is done to proper safety codes and that you can recoup some of the cost when re-selling, follow all the building permit codes of your community. Learn more about the importance of building permits.
Water Management
Is your basement dry? Any water leaks, mold, mildew or humidity issues need to be identified and repaired or managed before applying any new surface. Simply covering a damp concrete wall with drywall does not make the problem disappear; it only creates additional problems in the future like structural damage, mold and rot.
Basement Stairs
A finished basement is used more often, which means the stairs need special attention. Construction-grade or “rough finished” stairs often need to be completely rebuilt for correct riser height for finished tread material.
Safety Concerns
If there is no dedicated entry to the basement, you will be required to install an egress window or door. Egresses are for emergency situations so you can escape and firemen can get in. Learn more about egress windows.
New stairs and wall framing require fireblocking – which prevents movement of flame, smoke and gases through concealed vertical spaces – and draftstopping which does the same for horizontal spaces. Your communities’ building codes and remodeling professionals know the proper materials to use to keep your family safe.
Electricity
A basement remodel usually adds new features that require power, which means additional circuits need to be added to your electrical panel. You need a survey of new power needs and panel updates performed by a certified electrician.
HVAC
Proper and comfortable climate control in your finished basement might require an upgrade to the HVAC system. If you have an older system, this is the best time to upgrade to an energy efficient system for the entire house. But it is wise to tackle all HVAC upgrades before beginning construction work on the basement so you will have proper access to the furnace and air filters.
Utility Access
Your new walls and ceilings must provide easy access to water shut-off valves and plumbing stacks, electric junction boxes and gas lines. These utility items can be relocated at great expense, or simply include access panels and suspended ceilings in the new basement design.
Insulation
To increase comfort and energy efficiency, insulation and vapor retardation is a must. It is also a vast topic with many important details. For a quick primer on vapor retardation do’s and don’ts, click here. For pro tips on properly insulating a basement, click here.
Ceiling Height
Drywall or drop ceilings are common in a basement remodel, and a general rule of thumb is having a minimum of 7 feet from floor to ceiling. Each municipality has different requirements – as well as height exceptions for existing features like duct work and support beams – which will be thoroughly covered when applying for the building permit.
Flooring
Even in the driest basement, it is not recommended to use carpeting, hardwood or laminate flooring. Installation on concrete and variations in humidity can cause problems with these surfaces. Because of its resistance to moisture, tile of every kind is the preferred basement flooring material. Or consider painting the concrete the color your choice. Throw rugs can be used throughout the spaces for additional warmth and comfort.
All of the above is the short list of important details that go into the planning, design and building of a finished basement. Overlooking any of these steps is why so many do-it-yourself basement remodels eventually fail or – even worse – have to be ripped out come time to sell the home. It may seem that doing it yourself will save money, but doing it right (and safely) the first time with professional designers and builders always saves money in the long run.
