Lyman Has Doubled in 20 Years
Spray foam insulation in Lyman is mostly newer-home work. Lyman is a census-designated place in Harrison County north of Gulfport, and it has grown fast: from 1,081 people and 413 housing units in 2000 to 2,372 people and 1,005 units in 2020. That means most of the houses here are well under 25 years old, and plenty are much newer.
What newer homes need
A newer house usually has a reasonable amount of attic insulation on day one. Where we find room for improvement is air sealing and ducts: builder-grade ceilings with unsealed top plates and wire holes, recessed lights that leak, a pull-down attic stair with no insulation, and long flex duct runs in a hot attic. Sealing those, plus topping up to R-38 or more, is a common job. For homes with the air handler and ducts overhead, roof deck foam is worth pricing.
Rural lots and shops
About 71% of Lyman residents live in areas the census counts as rural, and that shows in the lot sizes. Metal shops, garages and storage buildings are common. Closed-cell foam on the steel walls and roof keeps them cooler and stops condensation dripping.
History
Lyman grew up around the railroad and two lumber companies, the Gulf Coast Lumber Company and Ingram-Day Lumber Company, and the federal government ran a fish hatchery there until 1973, when the state took it over. The timber-era houses are mostly gone; the town's character today is new homes on wooded lots. Get a free estimate

Lyman Questions
My Lyman home is only a few years old. Is it worth adding insulation?
Sometimes the best value is sealing rather than adding depth. We check the ceiling, the hatch and the ducts and tell you what would actually make a difference.
Can you insulate a new shop before I move equipment in?
Yes, an empty building is the easiest time. Let us know the size and panel type and we will price it.
What is the most common problem in newer Lyman attics?
Air leaks rather than a lack of insulation: unsealed top plates, wire and pipe holes, recessed lights and an uninsulated pull-down stair. Sealing those first makes the existing insulation work much better.
