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 crawlspace.
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 CrawlSpace 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 CrawlSpace:
- 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 crawlspace 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.

Crawl space encapsulation is essential for homeowners in Dover, NH, to shield their homes from moisture, mold, and pests. The local climate, which is often damp and humid, makes encapsulating your crawl space a valuable investment for both home durability and health. The encapsulation process involves sealing the crawl space to prevent water and moisture from seeping in, maintaining a dry and clean environment.
Why Choose Crawl Space Encapsulation?
Encapsulating your crawl space provides several advantages that go beyond moisture control:
- Prevents Mold Growth: Mold thrives in moist environments and can spread to other areas of the house.
- Improves Air Quality: Approximately 50% of the air in your home can originate from the crawl space. Keeping it dry and clean ensures healthier air.
- Protects Structural Integrity: Moisture can cause wood rot and structural damage over time. Encapsulation safeguards your home’s foundation.
- Energy Efficiency: A sealed crawl space enhances your home’s energy efficiency by reducing heating and cooling costs.
- Increases Property Value: Homes with encapsulated crawl spaces are more appealing to buyers, suggesting better maintenance and fewer repairs.
Benefits of Crawl Space Encapsulation
Encapsulation is a proactive step to protect your home:
- Humidity Control: Keeps humidity levels low to prevent mold and mildew.
- Pest Prevention: Seals the space, making it less attractive to pests like rodents and insects.
- Insulation: Adding vapor barriers and insulation helps maintain consistent indoor temperatures.
- Energy Savings: Prevents cold air from entering through the crawl space, reducing the workload on your HVAC system and saving on energy bills.
Crawl Space Encapsulation Process at 603 Basement Solutions
At 603 Basement Solutions, the process is comprehensive and tailored to each homeowner’s needs.
Initial Inspection and Assessment
The first step is a thorough inspection to identify issues such as water intrusion, mold, or structural damage. Technicians check for signs of moisture, mildew, and potential pest infestations. This comprehensive evaluation helps determine the appropriate action plan tailored to the specific conditions of the crawl space.
Cleaning and Preparation
Before encapsulation, the crawl space is cleaned thoroughly. Debris is removed, and any existing mold or mildew is treated with specialized cleaning solutions to ensure a sanitized surface. This step is crucial for ensuring that the vapor barrier adheres properly and functions effectively.
Installation of Vapor Barriers
A high-quality vapor barrier is installed along the walls and floor to prevent moisture from entering. This barrier is secured with special adhesives and fasteners to maintain its integrity over time. The vapor barrier is essential in creating a sealed environment that resists external moisture.
Sealing and Insulating
All vents, gaps, and holes are sealed with durable materials, followed by adding insulation to improve energy efficiency. This process prevents drafts and helps maintain a stable temperature within the home. Proper sealing also reduces the risk of pest entry and further moisture issues.
Final Inspection and Customer Education
After completion, a final inspection ensures everything is correctly in place. Technicians verify that all seals are secure and the vapor barrier is intact. Homeowners receive guidance on maintaining their encapsulated crawl space, including tips on moisture control and periodic checks to ensure long-term effectiveness.
Common Issues With Crawl Spaces in Dover, NH
Homes in Dover, NH, often face specific crawl space issues due to the local climate and soil conditions:
- Water Intrusion: Heavy rains and inadequate drainage can cause water to pool in crawl spaces.
- High Humidity Levels: The damp climate leads to high humidity, fostering mold growth.
- Pest Infestations: Rodents and insects are attracted to dark, damp, unsealed spaces.
- Structural Weakness: Continued moisture exposure can weaken the foundation and wooden structures over time.
Customized Solutions for Every Crawl Space
Every home has unique needs, and 603 Basement Solutions provides customized encapsulation solutions based on each home’s specific issues.

- Materials Used: Higher-quality vapor barriers and insulation may cost more upfront but offer better long-term benefits.

Dover crawl space encapsulation — local context
Dover sits low and wet, which is exactly why its crawl spaces sweat. The Cocheco River runs through downtown and, per Wikipedia/USGS, "below the center of Dover, the river is tidal and joins the Salmon Falls River… to form the Piscataqua" — a tidal, high-water-table setting that drives moisture up through dirt floors. Dover is also New Hampshire's oldest settlement (1623), and U.S. Census ACS data (Table B25034) shows 3,990 of 15,433 housing units — 25.9% — were built in 1939 or earlier, so fieldstone foundations and dirt crawl spaces are common here. That soil contact also invites radon: the EPA notes radon enters through gaps in suspended floors and around pipes, and causes about 21,000 lung-cancer deaths a year (action level 4 pCi/L). Encapsulation = a 12-mil wall / 20-mil floor vapor barrier + dimpled drainage matting + dehumidifier + sump. Crawl space encapsulation runs $3,000–$25,000. Radon mitigation, if needed, is a separate add-on, typically $1,950–$2,250. See our crawl space services and radon mitigation pages.
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
Why do Dover crawl spaces have moisture problems?
Dover is a low-lying river-and-tidal city. The Cocheco River runs through downtown and, per Wikipedia/USGS, becomes tidal below the city center before joining the Salmon Falls River to form the Piscataqua. That tidal, riverine setting keeps the water table high, and groundwater pushes moisture up through dirt-floor crawl spaces — especially in older homes. Encapsulation (a 12-mil wall / 20-mil floor vapor barrier plus dimpled drainage matting, a dehumidifier, and a sump) seals that moisture out.
Are Dover homes more likely to have old fieldstone or dirt-floor crawl spaces?
Often, yes. Dover is New Hampshire's oldest permanently settled community (1623), and U.S. Census ACS data (Table B25034) shows 3,990 of its 15,433 housing units — 25.9% — were built in 1939 or earlier. Homes of that era commonly sit on fieldstone or rubble foundations with dirt-floor crawl spaces, which is exactly the kind of work 603 specializes in for old New England homes.
Does a Dover crawl space need radon mitigation too?
Sometimes. A dirt-floor or unsealed crawl space sits right at the soil-gas source, and the EPA notes radon enters a home through gaps in suspended floors and around service pipes, causing about 21,000 lung-cancer deaths a year (action level 4 pCi/L). NH DHHS reports roughly 37% of tested NH homes exceed that level, with the Seacoast among the highest. If your home tests high, radon mitigation is a separate add-on, typically $1,950–$2,250.
