"We had a tremendous experience with JES Foundation Repair. Chad was the Certified Inspector, and the work crew was Mike Boines, Corey Griffin and Deontae Jackson. The initial inspection and estimate was thoroughly explained, all appointments were on time and every step in the process was discussed. All discussions were very professional. Foundation repair and sidewalk "lifting" were all completed with satisfaction."

Looking for a professional that will give you an honest price and the best craftsmanship around? Armour Home Improvement is the company for you! Call us today, we look forward to speaking with you (301) 570-8041 or (410) 489-6004! (Please note that we only do complete remodels and not single item projects).

"I selected Armour over other contractors bids for my basement remodel and I am very happy that chose them. During the bidding process they answered all of my questions quickly and thoroughly, their proposal was thorough and clear, and they were happy to discuss my ideas, thoughts and concerns. The crew that did the work was fantastic. Those guys are pros. The scope of work included all new framing and drywall (up to code, unlike before they came in), replacing that damn stucco ceiling with new drywall, upgrading the bathroom and kitchenette, new flooring, new basement door and replacing the ancient basement window, plus upgrades to the interior basement stairs and bathroom exhaust fans. Everything passed inspection and I am a happy customer. I would hire Armour again in a heartbeat. Many thanks to Rob, Christina, Rudolfo and everyone who worked on the project."

Foundation, basement or crawlspace waterproofing / encapsulations FAQs

Yes, crawl space encapsulation is a good investment. It improves your home's energy efficiency and air quality, boosting its value. With routine inspections and maintenance, encapsulation provides a long-lasting solution to moisture and pest issues. Regular check-ups protect your investment, enhance energy efficiency, and maintain your home's structural integrity. If your home is prone to pests or moisture seepage, encapsulating your crawl space is definitely worth it.

A vapor barrier is a thin sheet of plastic that prevents moisture from seeping into your crawl space, while insulation prevents unconditioned air from entering. Combining both insulation and a vapor barrier creates a dry, temperature-stable environment. Some insulation products serve both purposes, enhancing energy efficiency and protecting against moisture and temperature fluctuations.
