We also offer a SumpGuard maintenance program where we check the operation of your pumps and back up system including flushing out your system.

A properly designed waterproofing system can give you more livable space, relieve the health effects from damp building syndrome and provide peace of mind. We even handle the permitting for you!

    Foundation Repair

    Do you have floors that slant? Is water leaking through your foundation wall? Can you see cracks in the foundation? Do you have problems closing doors and windows? If you notice any of these warning signs, you need a structural and foundation repair specialist to check on your property.

    Depending on your needs, we have a variety of services to offer. We can reinforce foundations with rods, carbon fiber straps, or underpin to support footings or provide penetrating sealants and coatings. We can replace block, concrete and rubble foundation walls if your situation is dire. We can also mend and fill foundation cracks with epoxy and polyurethane foam so things don’t get worse.

    Don’t leave your foundation repair job to just anyone. These jobs have to be done carefully under the supervision of structural engineers with the proper permits and extensive documentation for insurance purposes and for future buyers of your home or property. All our foundation repairs come with a warranty on workmanship and materials and the solid design from trusted licensed Professional Engineers.

    Mold Remediation

    Do you have visible mold growth in parts of your home? Do you get frequent sinus infections or allergic reactions? Do parts of your home smell musty? These issues indicate you need mold remediation.

    Our mold remediation services start with a review and assessment of the findings. We will contain the infested areas to prevent cross contamination to other areas of the home and typically include the removal of damaged or non-cleanable stored items and building materials. It’s followed by HEPA vacuuming and an intense cleaning of those affected areas. We follow up with post-remediation inspection. Once the immediate problem is taken care of, we rectify the root cause, which may include installing permanent smart ventilation and dehumidification or fixing whatever water penetration issue is occurring.

    We don’t just relieve the symptoms like so many “blow and go” cut-rate mold remediators. We have Certified Moisture Control Professionals on staff, trained by NORMI, the National Organization of Remediators and Mold Inspectors, who don’t rest until they’re sure the mold won’t return. We back our work with a $100,000 Insurance-Backed 100% Protection Guarantee.

    Crawlspace Encapsulation

    Do you have a crawl space? Did you know about 50% of the air you breathe on your first floor comes from your crawl space? If you have damp, stale, musty air and suffer from allergies, perhaps you need some crawl space restoration.

    Crawl space encapsulation involves conditioning and sealing off the crawl space from outside unconditioned air influences. We use high grade vapor barriers, insect resistant insulating rigid foam boards, smart ventilation systems and sometimes incorporating dehumidifiers. dehumidifiers. This work creates a “bubble-like” environment where moisture, harmful gases and odors can’t get in. We bring the good air in and keep the bad air out.

    Don’t leave your crawl space unchecked and deal with mold, rot and bad air, from excessive moisture, putting your health and the integrity of your structure at risk. Stop the energy loss you may be currently experiencing from bad crawl space climates. Call us today for a FREE initial consultation.

    Moisture and Ventilation Control

    Have you found mold in your home? Do you feel like parts of your home, like the basement crawl space or attic, are damper than the rest of the house? Do you have pests coming into the home? Is your second floor much hotter than the rest of your home? All these problems are linked to moisture and ventilation issues.

    Moisture control is a complex process that involves all the systems of your home working together harmoniously. It’s “building science”, a knowledge and expertise very few home service contractors have. After a full inspection on every level of your home including the exterior, we identify the moisture and ventilation issues you currently have. Often, we install smart ventilation systems designed specifically for your space, with a series of sensors to read temperature and dewpoint both at the interior and exterior. In addition, we may add moisture-resistant coatings to your exterior coverings and foundation walls or encapsulate your crawl space and provide water management solutions to your exterior foundation and grade.

    Our Certified Moisture Control Professionals will do whatever it takes to make sure your home has proper protection from water damage. They’re trained by NORMI, the National Organization of Mold Remediators and Inspectors and have years of experience. Call today for a FREE initial moisture control consultation.
