Insulation & Crawlspace Help for Lewisville Homeowners
Lewisville is a small Forsyth County town on the western side of the county, next door to Clemmons and a short drive from Winston-Salem. Parts of it feel more spread out than the city, with homes on larger lots and plenty of trees, and its neighborhoods are less uniform than a single big subdivision.
Insulation Pros is a family owned and operated company in Winston-Salem, and Lewisville is one of the towns we serve. This page covers what tends to matter for insulation and crawlspaces in homes like these and how our free estimate visit works.
Our Services for Lewisville Homes
We install six services for attics and crawlspaces. Open any of them to see how the work goes, or call and we will help you sort out which one fits your home.
Crawlspace Encapsulation
A sealed vapor barrier, closed vents and moisture control that stop dampness, mold and musty odors.
Vapor Barrier Installation
A heavy-duty ground barrier that blocks moisture from rising into your crawlspace and home.
Crawlspace Dehumidifier Installation
A dehumidifier sized for your crawlspace so humidity, mold and wood rot stay under control.
Air Sealing & Duct Sealing
Sealing attic gaps and leaky ductwork so conditioned air stays inside your home.
Spray Foam Insulation
Spray foam for rim joists, additions and tight spaces that need an air seal plus insulation.
More Variety in the Houses Themselves
Where lots are bigger and neighborhoods less uniform, homes tend to be more individual too. You may have a custom-built house with several rooflines, a one-story with a large bonus room, a house that has been added onto over the years, or an older farmhouse-style home that predates the surrounding neighborhoods. Each of those has its own insulation story, so we do not assume a standard answer.
We look at your home, ask what you have noticed, and build the recommendation from there. Sometimes that is a single service. Sometimes it is a short list, in an order that makes sense.
Additions, Bonus Rooms and Complicated Rooflines
Additions and rooms above garages are frequent trouble spots for comfort. The new section may have been framed and insulated to a different standard than the original house, and the junction between old and new is full of small gaps. Complex rooflines create attics with sharp corners, knee walls and crawl-through sections where a blower hose cannot easily reach.
This is where spray foam earns its place. It expands to fill irregular gaps and seals air leaks at the same time, so it suits rim joists, small enclosed cavities and difficult corners. In the open, easy-to-reach parts of the same attic, blown-in insulation is usually the more practical choice. It is common for one home to call for both, each used where it fits.
If your home has vaulted or cathedral ceilings, the amount of insulation that fits is limited by the depth of the rafters and the need to keep air moving, which is another reason an in-person look matters before anyone recommends a material.
Shade, Leaves and Crawlspace Humidity
Heavily wooded lots keep the ground shaded, which slows drying. Leaves and debris collect against foundation vents and can hold moisture against the house. A crawlspace on a lot like that can stay humid through the summer even though nothing looks wrong from the yard.
There are simple things you can watch for. A musty smell in the house that is worse in summer, condensation on ducts or pipes if you can safely see into the crawlspace, and insulation that has fallen or looks damp are all reasons to ask for an inspection. If everything looks dry and sound, we will say so.
Gutters and downspouts matter more on a wooded lot than most people expect. Leaves clog them, and the rain that should be carried away ends up at the foundation instead.
Matching the Fix to a Lewisville House
The right mix depends on the house, but these are the services we most often discuss for homes in this part of the county.
- Spray Foam Insulation: for additions, rim joists and tight or irregular spaces that need insulation and air sealing together.
- Attic Insulation: blown-in fiberglass or cellulose across the open areas of the attic, brought up to an even depth.
- Air Sealing & Duct Sealing: closes the leaks at the joints between old and new construction and along leaky duct runs.
- Crawlspace Encapsulation: a sealed and conditioned approach for crawlspaces that stay damp under shade and leaf cover.
- Vapor Barrier Installation: a durable ground cover where soil moisture is rising into the space.

My house has an addition and several rooflines. Is spray foam better than blown-in insulation?
Neither is better everywhere. Blown-in insulation is usually the practical choice for open attic floors, while spray foam is often a better fit for rim joists, small cavities and awkward corners where an air seal matters as much as insulation. Many homes with additions use both. We look at how each part of your attic and floor is built before recommending materials.
How can I tell if my shaded crawlspace has a humidity problem?
Warning signs include a musty odor in the house that gets worse in summer, condensation on ducts or pipes, insulation sagging or falling from the floor, and dark staining or fuzzy growth on wood. Only look inside if you can do so safely. A visit from us can confirm what is going on, and if your crawlspace looks dry and sound, we will tell you that honestly.
