Crawl Space

Crawl Space Moisture & Pest Work: what it covers

Quick answer

A crawl space is the gap between the floor and the ground in a house on piers. Across Gwinnett the older crawl-space houses rest on brick or block piers, and the wood in soil contact is where termites, wood-decay fungi, roaches and rodents find shelter. A technician checks the standing water, the soil, the vapor barrier, the sills and the piers, and records what is found.

Crawl Space Moisture & Pest Work illustration for Snellville, GA

A crawl space sits between the floor of a house and the ground beneath it. Across Gwinnett the older crawl-space houses are typically on brick or block piers, and the space under the floor is where the sills, the band joist, the piers and any wood in soil contact are found. That space is also where moisture collects, which makes it the most important area for both wood-destroying organisms and household pests.

The pests that use a crawl space are not the same as the ones that use a slab house. Smokybrown cockroaches, which are the most widespread cockroach pest in the Southeast according to University of Georgia Extension, are tied to older neighborhoods and tree holes, and they can come in from the outside. Rodents such as the house mouse, the Norway rat and the roof rat all live in Georgia, and they use the same dark, damp space to move under a house. Wood-decay fungi use the damp wood. The work covers all three.

Phones are answered 24/7, so a call about a damp crawl space or a sound under the floor can be made when it is noticed. Visits are booked when a technician is free, and the price is explained and approved before any work starts. To describe what you have found under the floor, call (855) 974-4733.

Warning signs

Signs you need crawl space moisture & pest work

Do not enter a crawl space without a light, a clear way out and someone who knows you are there, and do not crawl through a space with standing water or a torn vapor barrier unless you have to. Do not handle a rodent nest or droppings with bare hands, and do not sweep or vacuum a crawl space in a way that stirs up dust. Do not tap or pry at soft wood to test it, because the damage can be worse than it looks. Keep pets and children out of the crawl space while work is underway.

  • Standing water or wet soil on the dirt floor after rain
  • A vapor barrier that is torn, displaced or lying loose on the soil
  • Soft or dark wood at a sill, a joist end or the base of a pier
  • Wood in direct soil contact, such as a post or a sill that touches the ground
  • Small holes with chewed edges at a sill or a vent, and droppings near stored items
  • Roaches or spiders in the crawl space, or a musty smell that comes up through the floor
  • Stored boxes, lumber or debris against the piers or the wall

Types and options for crawl space moisture & pest work

Crawl space inspection

A routine inspection checks the sills, the joists, the piers, the soil and the vapor barrier, and records any moisture or pest activity found. It is the starting point for any crawl-space work and it gives the homeowner a clear picture of the space before any treatment is planned.

Pest treatment in a crawl space

When roaches or rodents are using the crawl space, the technician treats the activity and its routes. Gel bait is placed in small dabs for roaches, and rodent work focuses on the holes and runs. Larger roaches may not fit inside a bait station, so the technician chooses the method for the species found.

Wood-in-soil-contact work

Where wood is in direct contact with the soil, the technician records each location and explains what is needed to correct it. The work may be a treatment under a termite contract, a repair by a contractor, or a note for the next annual inspection, and the diagram shows which.

What does a technician look for under the floor?

A technician looks for standing water, soil contact with wood, a torn or displaced vapor barrier, soft wood, and any sign of termites, wood-decay fungi, cockroaches or rodents. Each finding is recorded with its location.

The first things noticed are usually the conditions: water on the soil, wood that sits in the wet, and a barrier that no longer covers the ground. Those conditions favor both wood-destroying organisms and pests, so they are recorded before the activity is looked for.

Which pests use a crawl space?

Smokybrown cockroaches, the house mouse, the Norway rat and the roof rat all use the dark, damp space under older houses, and wood-decay fungi use the damp wood. Each has its own signs and its own route in.

Smokybrown cockroaches are tied to older neighborhoods with mature hardwoods, where they live in tree holes and leaf litter outside. They are active at night and rarely found in kitchens, which is why a crawl space is a common place to find them. Rats and mice usually hide by day and come out at night, and a small hole with chewed edges is a sure sign that an animal is using it.

Why does moisture matter under the house?

Moisture is one of the conditions that favor subterranean termites and wood-decay fungi, and it attracts many of the pests that use a crawl space. Standing water and wet soil are the conditions a technician records first.

Wood that stays damp is more likely to be affected by decay and by termites, and wood in direct contact with soil is the most exposed. The technician notes where water pools, where the soil is bare and where wood touches the ground, since those are the places the moisture is doing its work.

What about older crawl-space houses in the nearby towns?

The older stock in Lilburn, Monroe and Oxford, along with the older parts of Lawrenceville, is where crawl-space houses on brick or block piers are most common. The wood under those floors is closest to the soil.

Those houses often have dirt floors, older sills and piers that have been in place for decades. A technician checks each of those elements in turn, and the diagram records the condition of each one. Where a repair is needed, the technician says so, and where a treatment is needed, the contract covers it.

What moves the price up or down here?

Clearance, standing water, the size of the crawl space, the number of piers and sills to check, and whether a pest or termite treatment is needed shape the price. No figure is printed on this page, and the price is explained and approved in writing before any work starts.

Low clearance and standing water make the work slower and sometimes require a return visit once conditions change. A larger crawl space has more sills, piers and wood to check, and a dirt floor adds the soil to the record.

Our process

How our crawl space moisture & pest work visit works

  1. Enter and check access

    The technician checks whether the crawl space can be entered safely, how much clearance there is, and whether standing water or a loose vapor barrier is present. The access is noted first because it sets what can be inspected in the time available.

  2. Check the moisture and the soil

    The technician looks at the soil, the standing water and the condition of the vapor barrier. Soil contact with wood, damp areas and any pooling are recorded, since those conditions favor both termites and wood-decay fungi.

  3. Inspect the sills, joists and piers

    The sills, the band joist and the piers are checked for soft or dark wood, for damage and for signs of activity. Wood that is in direct contact with the ground is noted separately, because it is the wood most likely to be affected.

  4. Look for pests and their routes

    The technician looks for cockroaches, rodent signs and the routes they use, such as holes with chewed edges at sills and vents. Droppings, gnaw marks and trails are the most useful evidence, and they point to where a repair or a treatment is needed.

  5. Record the findings and explain the plan

    Each finding goes on a diagram with its location. The technician explains which conditions need to be corrected, which need treatment and which need a repair by someone else. The price is explained and approved before any work starts.

Gwinnett County

Why crawl space moisture & pest work is different in Gwinnett County and the east Atlanta suburbs

Gwinnett's older houses are part of a mixed housing stock. Across the Gwinnett County school district geography, most structures were built between 1970 and 1999 and only a small share before 1970, so the inspection starts by identifying which kind of foundation is in front of the technician.

The older stock is concentrated in specific towns, including Lilburn, Monroe and Oxford. In Monroe, the courthouse square and historic districts have older houses, and in Oxford the older blocks date from the college era. A crawl-space plan in those places has to account for the age of the wood as well as the moisture.

FAQ

Crawl Space Moisture & Pest Work FAQs

What is a crawl space?

A crawl space is the shallow void between the floor of a house on piers and the ground beneath it. In Snellville the older houses are typically on brick or block piers, and the sills, the band joist, the piers and the soil all sit in that space.

Why are cockroaches and rodents found in crawl spaces?

The dark, damp space offers shelter, and smokybrown cockroaches and rodents use it to move under a house. Smokybrown cockroaches live in tree holes and leaf litter outside and can come in, and rodents hide by day and come out at night.

Can a technician tell if the wood is damaged?

A technician can see soft or dark wood and can test it in a limited way, but the full extent of any damage is not always visible. Where visible evidence exists, the report says that some damage should be assumed, and a qualified evaluation can follow.

Does this service include a moisture reading?

The inspection records standing water, wet soil, soil contact with wood and the condition of the vapor barrier. It does not give a moisture figure or a rule for vents, because the right answer depends on the house and the technician explains what was found.

Is a torn vapor barrier a problem?

A torn or displaced vapor barrier leaves the soil partly exposed, and it is recorded during the inspection. The technician explains whether the barrier affects the findings and who should repair it, since a barrier repair is often a separate job.

What if the crawl space cannot be entered?

The report says the space was not inspected and gives the reason, such as low clearance or a locked hatch. The homeowner can arrange access and ask for a return visit, and the limit is written into the record.
