What is CrawlSpace repair?
The crawl space is one of the most hidden parts of our homes. It’s a place that we don’t usually see and often forget to clean or check. But it is an essential part of our home because it provides space for HVAC, plumbing, and electrical. Most importantly, it keeps the wooden aspects of your foundation from resting in dirt/water from the elements.
Your crawl space can be a great place to store your holiday decorations or pack away winter clothes. These are some of the benefits for homeowners who have hired 603 Basement Solutions to encapsulate their crawl space.
As with any other part of your house, when you find issues in your crawl space, it’s time for repair. If you don’t take care of these problems promptly, you may be facing more serious consequences later on down the line.
Causes of Crawl Space damage
There are many reasons why your crawl space may end up flooded with water. A few common causes include sitting water damage in your crawl space, sloped floor crawl space damage, and mold or mildew crawl space damage.
Moisture is the most common cause of crawl space damage. When moisture accumulates in the crawl space, it can cause the floor joists to rot, wooden beams to warp, and drywall or plaster to crack. Eventually, the wood can rot and give way, which poses a safety hazard for those living above it.
There are 3 main causes of moisture build-up in your Crawl Space:
- When a house is built on a wet site (i.e. where water pools).
- When natural ground slopes towards the house and lets water seep through its foundation.
- When there is not enough air circulation in the crawl space.
Humidity is a major cause of crawl space damage. When the relative humidity in a house rises to a certain level, it can begin to damage the structure’s foundation, which includes the insulation floor joists and vents that are located under the house.
Dry rot is another common cause of crawl space damage. This occurs when there is too little moisture in the environment for wood to remain healthy and keep its shape.
Termites are yet another reason for crawl space damage, as they can quickly eat away at wood from under your home.
Water intrusion is also an issue that can be attributed to damage in your crawl space. Tightening up the perimeter drainage systems below the home and keeping gutters clean will help remedy this potential problem.

A crawl space is an enclosed area beneath a building that is not intended for human entry. These crawl spaces are typically unventilated and lack sufficient insulation, making it difficult to regulate temperature or maintain the right humidity levels. The result can cause a variety of problems including mold growth, pest infestation (such as termites), and rot.
Crawl spaces are often dark, dirty, damp, and filled with mold. The floors are often slippery and uneven. This makes it important to hire an expert who knows what they’re doing.
For example, a professional can identify the major sources of moisture or dampness in a crawl space before fixing them for you – without costing you an arm and a leg in repairs! A professional will have the expertise and the resources needed to assess the situation and take appropriate action to prevent or remove any potential health hazards from your crawl spaces.

Concord crawl space encapsulation — local context
Why do Concord crawl spaces stay damp? Geography. Per Wikipedia, downtown Concord sits on a low terrace within the Merrimack River valley floodplain — a setting that keeps the seasonal water table high and pushes ground moisture up into your crawl space. NOAA/NCEI 1991–2020 normals put Concord at about 42 inches of precipitation a year, so rain and snowmelt keep recharging that table. And per the U.S. Census Bureau (ACS 2024, Table B25034), 33.0% of Concord's housing — 6,359 of 19,259 units — was built in 1939 or earlier, exactly the fieldstone-foundation, dirt-floor crawl spaces we specialize in. Our crawl space encapsulation seals the space with a 12-mil wall / 20-mil floor vapor barrier, dimpled drainage matting, a dehumidifier, and a sump. Encapsulation runs $3,000–$25,000. Since Merrimack County is EPA Radon Zone 2, the crawl is also a soil-gas entry path — radon mitigation is a separate add-on, typically $1,950–$2,250.
What a recent customer said
"Gerald and his crew did an excellent job, first cleaning out all the debris and the dislodged insulation in the crawlspace. they were very communicative and understood my concerns and handled them professionally. When they were finished laying the sublayment and the top vinyl covering, carefully taping all the seams they put insulating foam around the perimeter, sealing the top of the vinyl. Gerald communicated two issues that were not part of the contract that I will subsequently take care of myself. Great job, very satisfied." — Alex C Arcisz, 5★ (Google review)
Frequently asked questions
Is radon a concern for crawl spaces in Concord, NH?
Yes. Concord is in Merrimack County, which the EPA Map of Radon Zones classifies as Zone 2 — moderate potential, with a predicted average indoor screening level between 2 and 4 pCi/L. An open or dirt crawl space is a direct soil-gas entry path, which is why we seal it. The EPA advises testing every home regardless of zone and fixing at 4 pCi/L or higher. Radon mitigation is a separate add-on from encapsulation, typically $1,950–$2,250.
Why are Concord crawl spaces prone to moisture?
Two local drivers. Per Wikipedia, downtown Concord sits on a low terrace in the Merrimack River valley floodplain, which keeps the seasonal water table high. And per NOAA/NCEI 1991–2020 normals, Concord averages about 42 inches of precipitation a year, so rain and snowmelt keep recharging that table. Without a sealed vapor barrier and dehumidifier, that moisture migrates up into the crawl space.
Does crawl space encapsulation suit Concord's older homes?
It's a strong fit. Per the U.S. Census Bureau (ACS 2024, Table B25034), 33.0% of Concord's housing — 6,359 of 19,259 units — was built in 1939 or earlier. Those pre-war homes are the ones with fieldstone foundations and low-clearance dirt crawl spaces, exactly what encapsulation is designed for. Encapsulation runs $3,000–$25,000 depending on size and condition.
