Determining the cost of foundation repair for your crawl spaces is simple. You just need to know the measurements of your crawl space (if you have one), and these numbers can be used to estimate the cost of repairs. A lot of homeowners make the same mistake with their foundation repair estimates; they often choose to hire an estimate provided by a professional foundation repair company. Unfortunately, not all companies provide quality service.
A crawl space is usually an unfinished, unventilated, narrow passageway inside a building, usually between the second floor and the ground level. The term ‘crawl space’ is also used to describe basements that are below grade. The term ‘crawl’ is generally used in association with sewer systems and drains. Typically a crawl space has no plumbing or electrical outlets and so must be drained and sealed off from the outside environment. The term ‘crawl space’ is also used to describe pre-construction buildings that have many ceiling cracks that are not evident on ground level.
In most cases, a crawlspace will be perfectly safe, even though it is below ground level and therefore exposed to moisture and industrial waste products. If the foundation of your home is settling or moving, or the foundation may already be failing, you may have no choice but to address potential basement mold problems before they become serious. Professional foundation contractors can seal and waterproof your crawl spaces – even if there are only a few damp walls – to make sure that water damage does not get worse. If your home is currently undergoing a remodel, then the contractor should contact a certified mould inspector to discuss the possibility of moisture problems in your basement.
Why do homes have a crawl space? Crawl spaces are designed for a purpose: to provide an area for storage underneath the house. For houses that have already been built, often because the original construction did not include a room for the foundation or other structure needed to support the load of the house, a crawl space becomes an important part of the HVAC (heating, ventilation, air conditioning) system. Since most new homes contain concrete floors, which absorb heat from the earth’s surface, the HVAC system is built right into the concrete and absorbs the moisture that occurs during normal daily use.
When home construction began, most homes were built with slab foundations. However, after World War II, many homes were built with tile or concrete block walls. These walls did not hold up well against moisture, and the home’s foundation also started to wear down. To remedy these issues, builders started using polystyrene sheeting as wallboard, which was lighter and more moisture resistant than concrete slabs. Now, crawl spaces are being utilized as extra storage areas for garden tools, outdoor appliances, pool equipment, and other items.
In addition to the issues that occurred with slab foundations, homes with crawl spaces also tend to have more electrical wiring than homes without these. Since basement walls are usually completely enclosed, there are no outlets and plumbing outlets in the crawl space. In many cases, electrical wiring is installed over the concrete walls, so water can build up behind the walls and freeze inside the walls, causing electric shock and fire. It is important to note that, where water accumulates, it needs to be drained immediately, since stagnant water can expand and cause a foundation crack. Many times this requires digging a small hole and then draining the water out; this method works in many crawl spaces.
A vapor barrier system is used to prevent this problem, since the walls are sealed and moisture is vented outside of the house. The vapor barrier system consists of two layers: the exterior vapor barrier, which are placed on the outside of the crawlspace, and the interior vapor barrier, which are placed inside the space. Both of these barriers work together to prevent moisture from building up behind the walls, and they also work to keep the walls dry. By putting in a vapor barrier system, you can ensure that your crawlspace will remain dry.
A very common complaint with basement walls is that they are not sealed. In many cases, if there are cracks in the walls, they are not sealed correctly. If there are visible signs of water damage such as bubbling paint or walls that are peeling, the walls are often improperly sealed. Sealing can also prevent moisture from getting behind your drywall, which can cause warping and cracking. sealing your crawl spaces will not only make them look better, but will ensure that they are safe for your family.
