Inspections & Detection

Finding the source of the problem during your inspection is what is most important because without finding the cause, you cannot properly fix the problem.  Sometimes water and mold hide themselves very well and can go unseen and cause a lot of damage.  Our technicians don’t stop until we uncover the root of the problem, the result is that you know that the problem will be resolved for good!

Removal & Remediation

MOLD REMEDIATION – We have performed mold remediation for over 20 years. From a small laundry room project to serving on the national disaster team for Katrina.  It’s essential to have extensive experience in mold inspection because many times the damage can be unseen. We understand the mold growth patterns which allow us to properly estimate the mold removal cost.  In addition to mold, we have moisture solutions for your foundation, your yard, or our innovative solutions for drying out your crawlspace. And to make sure your home is 100% healthy.


STRUCTURAL REPAIR – As a Class A Contractor with the State of Virginia, if we find that you have structural problems, we are able to deal with it immediately.  Whether replacing rotted out joists, beams or subflooring, we have the experience and plain old know-how.

You are fully protected by our 100% Satisfaction-Guarantee.

We’re incredibly proud of our workmanship. We stand behind our work 100%.  The quality of our service is Top-Notch! Our promise to you is this:  If you ever have a problem with a solution we have put in place, just call us and we will make it right!

    "I had the smell of mold in my house"

    I called because I had the smell of mold in my house and standing water in my crawl space. Gilbert and Son came out and did a free estimate. After I booked the job, they were on time professional, and cleaned up after themselves. The work and price was spot on. I highly recommend this company to anyone in need of mold or crawl space work.

    "I’m so happy I called them"

    Had some structure issues in my crawl space so originally I called a local termite company, they came out and said I had a eight rotted beams and a bunch of broken floor joists. They gave me a $20,000 estimate so I called Gilbert and Son for a second opinion. The owner Mike came out and looked in the crawl space and informed me that I had one rotted beam and two broken floor joists and then explained why that was causing my floor to sink. They were able to fix everything and install a new vapor barrier for under five grand. I’m so happy I called them and escaped being ripped off by the termite company. The technician Paul and his helper were very clean and professional and did a wonderful job. Highly recommend this company. Keep up the great work guys!

    "My termite inspector even commented on how well done it was"

    Very professional. They did an excellent job! My termite inspector even commented on how well done it was.
