Crawl Space Moisture Control for Portsmouth Homes
Coastal humidity condenses under Portsmouth homes, feeding wood fungus and softening the framing over your crawl space.
Our technicians install moisture barriers and treat fungus before floors start to sag.
Portsmouth sits low and close to the water, so the air trapped in vented crawl spaces stays heavy with moisture year-round. That dampness condenses on joists and subfloors, invites wood-decay fungus, and slowly weakens the framing until floors sag and doors stick. Older homes in Olde Towne and Cradock, built on brick foundations with open vents, are especially prone to it. Left alone, the moisture also draws termites, roaches, and crickets deeper under the house.
We inspect the crawl space for standing water, condensation, and fungus, then install moisture barriers and treat the wood-decay fungus already at work. Controlling the humidity protects the structure and removes the conditions that pull moisture pests in. We follow up to confirm the space is drying and the treatment is holding. The guarantee that covers our pest treatments covers this structural work too.

| What to compare | Universal Pest Control | Most pest control companies |
|---|---|---|
| UniGuard ProgramExclusive | Universal Pest Control Termite protection and full pest control combined in one membership for one low monthly payment — from $59/month, with the termite warranty and quarterly pest service included together. | Most pest control companies Termite protection and pest control are usually sold as two separate agreements, with two renewals and two bills to keep track of. |
| SmartPay financingExclusive | Universal Pest Control $0-down payment options on termite treatments, baiting systems, and repairs, so the work can start before payday. Simple, predictable monthly payments. | Most pest control companies Financing, where it is offered, is commonly arranged separately through a third-party lender. |
| Pest Guard Attic Insulation™Exclusive | Universal Pest Control Hampton Roads' only licensed Pest Guard Insulation™ installer, through our sister company Universal Insulation Doctor — insulation manufactured with an EPA-registered pest preventative, so the replacement itself resists the insects that ruined the original. | Most pest control companies Attic insulation is typically referred out, and standard fiberglass has no pest deterrent built into the material. |
| Total Home Health Network | Universal Pest Control Pest and termite control, attic insulation, and duct cleaning coordinated under one roof through the Universal family of companies — one point of contact for the whole job, done in the right order. | Most pest control companies Pest control only.

| Family owned & operated | Universal Pest Control Owned and run by a family that has lived in Hampton Roads their whole lives.

Free inspections, plus same-day and next-day service. | Most pest control companies Retreatment terms, callback windows, and what counts as covered differ from contract to contract. |
