Precautions to Protect Our Customer's Property

To deliver the best and safest service possible, the 3 Pros team takes extra precautions when working on-site to ensure that our customer's property is well-protected. Some added precautions we take include laying tarp over the driveway to prevent any debris from collecting on it and using fans and layflat ducting to push air out of the work space. This creates negative pressure so that dust is contained in the work space and does not get into upper levels of the property.

Crawlspace is wet. Part of it is a large space that I would like to use for storage.

Bought a house that needs new crawlspace insulation and some joist repair
Vicinity of E Reed Ave in Alexandria
Damp basement. Moist seeps through basement walls causing smell and mold, and damage to floors. One wall is shared with a neighbor.

Looking to have foam sprayed in space between basement ceiling and floor above
Vicinity of Edison St in Alexandria
Floor joist repair for extensive termite damage that happened before I bought the house. I had a structural engineer come out and he determined the supports in the crawl space weren't properly fixed. Over the last year, the floor has started to drop causing the stairs to tilt and walls to lean and crack.

Water in basement
Vicinity of Curtis Ave in Alexandria
Looking for an estimate for a whole basement de-humidifier. My basement is finished and approx. 800 sqft. I currently have a portable de-humidifier hooked up o my sump pump. It is noisy and I feel like it struggles when the humidity levels rise. I'm also interested in how much carpeting about 600 sqft of the basement would cost with your products. Looking to have the basement re-carpeted but dont want to worry about mold down the line. Please reach me by email as I dont have regular access to my phone throughout the day. If you could also give me approx. prices in your email I would greatly appreciate it. Thanks!

I am the original owner of a 20 year old house with a finished basement. Recently we had water penetration below window wells, less than a gallon in each of two rooms. The house has a french drain system with black pipe in most of the wells. In removing carpet and drywall, I find some rust on carpet nails, which suggests this wasn't the first time water had penetrated the rooms, but there has not been a mildew problem in the past.

Vicinity of Old Dominion Blvd in Alexandria
I bought the house about a year ago and just discovered that the crawl space was not fully sealed or encapsulated. I would like someone to come make sure the insulation is still good, repair if necessary, and encapsulate.
