Happy Holidays to healthy Homes

The organized chaos of the holiday season has people running frantic to tackle everything left on their 2013 checklists. Keeping up with your holiday lists are hard enough on their own. buying gifts, planning get-togethers and travel arrangements are all part of the holiday norm. As you check items off of your lists, we encourage everyone not to forget about the to-do lists for your home as well. Let me explain to you what I'm talking about.

Roseburg, OR - December 12, 2013

Basement Waterproofing: Water in basements is as old a story as the structures themselves. Water leaks through any opening possible, including walls, floors, and any joints in between which can cause basement flooding and severe damage to your home and belongings. Water can also come through the basement concrete itself. With the right tools and the right minds, together we can keep your basement dry ALL the time.

Crawlspace Encapsulation: Your home is a big system and every part of it has a role that affects the rest of your home. If your crawlspace shows signs of rot, mold or structural problems, this can spread to other parts of your home which can affect you and your family. At TerraFirma Foundation Systems, we specialize in crawlspace problems of all sorts, whether you have mildew, sagging crawlspace ceilings or other problems.

Foundation Stabilization: Foundation problems can show themselves in many different ways throughout the home including cracked concrete, bowing walls, settling floors, and drywall cracks. Our certified foundation experts are here to fix your problems. We have the training, the know-how and products to solve your home's foundation problem.

Concrete lifting and leveling: Does your driveway, sidewalk, walkway, concrete steps or patio have a problem area where sunken concrete has caused uneven surfaces and trip hazards to form? This is a very noticeable problem that has a very simple solution. By injecting a lightweight polyurethane, called PolyLevel, into sub-concrete slab voids, we can restore driveways, sidewalks, walkways, and concrete slabs back to normal at a fraction of the cost of getting them fully replaced. 

Providing service throughout the state of Oregon and south west Washington, we are the region's expert in everything basementy. Start the new year off on the right track and protect your largest investment. Your home! Increase market value and enjoy the benefits while you see your investment grow.

As always, from everyone at TerraFirma Foundation Systems, have a safe and joyous holiday season.
