Q: What causes a basement to smell musty?

• <div><p>Mold and mildew are the things in basements that actually cause the musty odors, but moisture is the underlying issue that causes mold and mildew growth. Addressing moisture and water problems and then removing materials that are moldy are some of the best ways to get rid of the musty odors. Preventive measures after that&mdash;like installing air fresheners and a dehumidifier&mdash;can help keep musty odors from returning.</p></div>

Q: What can I use instead of crawl space encapsulation?

• <div><p>Venting the crawl space can be a good alternative to encapsulation if you live in a dry climate and the moisture problem isn&rsquo;t severe. You could also try a dehumidifier or install a vapor barrier on the floor, leaving the walls exposed. A new drainage system may eliminate the moisture problem if it is not caused by humidity.</p></div>

Q: How do you make a homemade water barrier?

• <div><p>Sandbags are the most common and efficient way to create a flood barrier at home. Some local authorities pass them around to homes before the risk of a flood. Otherwise, you can use flood-proof house materials, like burlap or woven plastic bags, to make sandbags and fill them with sand or cat litter. Make sure that when you stack them, they&rsquo;re tightly laid on top of each other, creating the effect of a firm wall against accumulating water. </p></div>

Q: How long does foundation sealant last?

• <div><p>You&rsquo;ll need to reseal the foundation <b>every five to 10 years, </b>depending on the sealant you&rsquo;ve used, the moisture conditions present in and around your home, and the condition of your foundation. Having a foundation inspection conducted before reapplication can help you catch any problems before you begin resealing. Of course, if you notice any new leaks or other moisture problems at any time, it may be necessary to reseal the foundation sooner.</p></div>

Q: What happens if water gets under your house?

• <div><p>Standing water under your house can threaten its structural integrity. If water pools in your crawl space, it can damage the foundation and the structure above ground, causing wood rot, mold, and other problems. If you have a concrete foundation, standing water under your house can also make your foundation slabs crack.</p></div>

They kept me informed during the entire basement repair and finishing process. They came when they said and did what they said they would do. The quality of their work was outstanding. Dry wall, tape. Paint. Doors and frames and lvp glued down. Great service and great people.

We had our basement egress windows replaced by RBA. They were always on time, communicated every few weeks with updates and completed a clean and efficient install. When we decide to replace the upstairs windows, we will definitely use them!

The two girls were on time and did a good job cleaning. We had a lot of dust due to some painting and sanding so it took a long time to get all of it cleaned up. As a result, they were only able to get the main floor cleaned and not the basement. I was happy with the results and next time the...

They were great to work with. Quick, efficient, shared all information up front and throughout my project. This was a rather odd basement project in a 100 year old house and I really appreciated their attention to detail. Great job.

"My certified inspector MatthewCote out of the Belgrade, MT office found i have a natural spring comming up in my crawlspace. I knew I had water streaming all over crawlspace and my husband believed it was due to watering lawn of the hill our house sits on. Matt was great to work with, he was totally professional. He explained my situation and showed me in photos and map of my basement what this ssprincause, how it had eroded and damage caused. It has been going on for quite a few years, of which I noticed escalation of water even though I decreased watering on above lawn. I wish I had researched this sooner. But MATT assured me it's not too late. He was clear and concise as to what I needed done to resolve and eliminate further damage by installing 2 sump pumps, installing trenches & piping to drain all areas of water, draining ouside of house past septic and leach field, add a humidifier and encapsulation of crawlspace. I highly recommend Groundworks and Matt to anyone."

"At first Bob was attentive to his commitments, but was slow to finish at the end. All went well with his initial explanation of our situation and proposed solutions to the finishing of the concrete. Bob had a hard time finishing the details and lost a lot of my confidence at the end. It took over a year to get the job finished."
