Attic Insulation in Dallas, TX
Attic Insulation for Dallas Homes
Dimensional Contracting is an insulation contractor working out of Arlington, and Dallas is inside the area we cover. What we insulate is attics. That means blowing fiberglass or cellulose across the attic floor, fitting batts where the space suits them, taking out material that has failed, sealing the air leaks underneath it, and getting the ventilation working again.
Most people call because a room runs hot, or the bill keeps climbing, or somebody went up there and did not like what they saw. All three are worth looking into. None of them proves the attic is the problem. Leaking ducts, an air conditioner near the end of its life, west-facing glass and a poorly sealed ceiling all feel the same from inside the room. What your attic is actually contributing is something you measure, not something you work out from below.
So that is where we start. We get into the attic, check the depth in several places rather than one, look at the condition of the material, and then tell you what we would do and why. If it does not need work, we will say so. The attic evaluation is free. Call (817) 502-9282.
Our Services
What We Do in Dallas Attics
When we insulate, we insulate the whole attic rather than patching one area. If pests or a leak have damaged part of it, we check the condition of the existing insulation across the attic floor before recommending anything. Depending on what we find, it is either more material across the whole floor, or the old material out and new in.
That does not mean every attic needs stripping. Most do not. It means we will not blow new insulation over a wet or contaminated patch and call it finished.
Attic Insulation
We install and upgrade insulation in existing homes. It goes across the attic floor, from the eaves in to the hatch, worked around wiring and ductwork rather than stopped short of them.
How much you need depends on what is up there now and how deep it is, which is what the evaluation settles. Residential attic insulation explains how we measure an attic and what we recommend from it.
Blown-In Fiberglass and Cellulose
We use blown-in fiberglass and cellulose to insulate attic floors in existing homes. The material is blown through a hose, so it reaches the corners, works around joists and ductwork, and covers the parts nobody can crawl into.
Cellulose is denser and reaches a given R-value in less depth. Fiberglass is lighter and settles less once it is down. Either way it goes in across the whole floor to the depth in the estimate, so the attic ends up at one even depth. Blown-in insulation in Dallas covers the materials and the method.
Adding More Insulation
If what is already there is dry, clean and simply too shallow, blowing new material over the top is the cheaper route and it works properly. We check that it is dry and clean first, because new insulation laid over wet or contaminated material hides the problem rather than fixing it.
Recommended attic R-values have risen over the years, so a house insulated when it was built can sit below what is recommended now. Age on its own does not decide it. Depth and condition do. Adding more insulation sets out when topping up is enough and when it is not.
Insulation Removal and Attic Cleanout
Old insulation comes out when it is wet, contaminated, or carrying rodent droppings and nesting. We take it out with commercial vacuum equipment.
Clearing and sanitizing the attic floor is part of that job. With the floor bare, the framing and the ductwork are far easier to look over than they are under a layer of old material. Insulation removal explains how the job runs and where the old material goes.
Insulation Replacement
Replacement is those two jobs in sequence: the old material out, the floor cleaned and looked over while it is clear, then new blown-in material in at the depth the house needs.
It is the right call when what is up there is contaminated or soaked rather than simply thin. Attic insulation replacement sets out how we decide between the two.
Attic Air Sealing
Insulation slows heat moving through a surface. It does nothing about air moving through a gap, which is why sealing is worth doing before new material goes down and awkward to do afterwards.
Air gets through wherever something passes through the ceiling: plumbing stacks, electrical penetrations, top plates, open chases and the attic hatch itself. We close them with foam sealant and caulk. Attic air sealing shows where to look.
Attic Ventilation and Soffit Intake
Air should come in low at the soffits and leave high, and that only works if the intake is clear. Soffit vents can end up buried under blown insulation or painted shut, and neither shows from the ground.
We check that the soffit vents are open, clear the ones insulation has buried, open up soffit intake where the eaves allow it, and set baffles so new material cannot smother it. Attic ventilation goes through how intake and exhaust work together.
Attic Fans, Electric and Solar
We install attic fans, both electric and solar. Whether one belongs in your attic depends on how much intake it already has, because a fan pulling harder than the soffits can supply will take its air from the house instead of from outside.
A fan is not a substitute for insulation and it will not fix an attic that is short of intake. If a fan you already have has stopped, we will come and look at it and tell you whether it is worth replacing. Solar fans we install, repair and replace too. On an electric fan we replace the unit rather than swapping the motor, so a motor-only swap is not a job we take. Attic fan installation in Dallas sets out what is included.
What Decides the Recommendation and the Estimate
We do not publish a price per square foot. We measure the attic and give that house its own estimate, because the price is set by the attic rather than the city, and the five things below change from one attic to the next.
- How much attic floor there is to cover. This is the biggest single factor, and it is not the square footage of the house. Depending on how the house is laid out, the attic floor can be a different size from the total living area.
- Whether the old material comes out. Removal is its own job, with its own labour, equipment and disposal. Adding over what is already down costs less than taking it out and starting again.
- The depth you are starting from and the depth the attic should reach. Bare joists to a full depth is a lot more material than topping up a layer that is already halfway there.
- Access. A pull-down stair in a hallway is straightforward. A small hatch at the back of a closet, or a roof pitch too low to stand up under, adds time to every part of the job.
- Whether air sealing and baffles belong in the same visit. Both are cheaper while the attic is open and awkward to come back for.
Insulation is rated in R-value rather than inches, and depth on its own will not tell you the R-value, because that depends on the material and how far it has compressed. ENERGY STAR recommends R-49 for an uninsulated attic and adding about R-38 where three or four inches are already down. It gives the same two figures for climate zones 2 and 3. Those are its recommendations for existing homes, based on the 2021 energy code table, not a reading of your particular house.
Worth asking whoever quotes you, us included: what depth is going in and what R-value that works out to, whether the price includes taking the old material out, whether the soffit vents will be baffled, and whether a per square foot figure means attic floor or house floor. Two quotes that do not answer those questions are close to impossible to compare.
What We Do Not Take On
Worth saying plainly, so nobody wastes a phone call. We do not install spray foam insulation and we do not install radiant barrier. On an electric attic fan, we do not swap the motor on its own.
We do not take on duct work. We do not offer attic cleaning on its own. Cleaning and sanitizing come only with a complete insulation removal and replacement: once the old material is out, we clear the attic floor and sanitize it before new insulation goes down.
If what your house needs is outside that list, we will tell you rather than quote for it. Every service we offer is set out on one page.

Frequently Asked Questions
How much does attic insulation cost in Dallas?
We price each attic after measuring it rather than from a per square foot figure, because the amount of floor, what is already on it and whether it has to come out all change from one attic to the next. If you want a quick sense of where yours will land before anyone arrives, three things tell you most of it: the footprint of the attic floor, roughly how deep the existing material is, and whether it looks dry and clean or wet and disturbed.
Have those and the conversation gets a lot shorter. We still measure before quoting, and that visit costs nothing.
Can you add to the insulation that is already there, or does it have to come out?
Condition decides it, not age. Insulation that is dry and clean can usually be topped up. Insulation that is wet or contaminated comes out first. New material laid over it covers the problem without dealing with it, and neither option fixes the leak or the pests behind it. Compacted insulation is not automatically a removal job. We check how far it has packed down and what that has done to its condition and how well it insulates, then recommend one or the other.
You can see a little of that from the hatch, and it is worth a look: whether the material is even or scattered, light or stained, whether there is a smell. Take it as a reason to have it checked rather than an answer. Telling old dust from a moisture problem is not something anyone can do from the doorway. Look from where you are standing, leave the material and the wiring alone, and let us measure it. That visit is free.
Do you do attic cleaning and decontamination?
Only as part of a complete insulation removal and replacement. It is not something we sell on its own. When the old insulation comes out, the floor gets cleared and sanitized before the new insulation goes down.
If cleaning is the only thing you think you need, the useful first step is still getting someone up there to look. Contaminated insulation almost always has a cause, and the cause is usually still there once the mess is gone. Insulation removal explains what that job involves.
The upstairs runs hot in summer. Will more attic insulation fix it?
Sometimes. Often it helps without finishing the job. A hot upstairs room has more than one possible cause and insulation is only one of them. Leaking or undersized ducts, an air conditioner past its best, west-facing glass and air leaking up through the ceiling will each make a room feel like that, and adding insulation over a leaking duct does very little.
What we can tell you is what the attic side looks like: how deep the insulation is, what condition it is in, where the ceiling is losing air, and whether the ductwork up there is obviously in trouble. Ducts and air conditioning are not our work, so if that is where the problem looks to be, we will say so rather than sell you a job that does not fix the complaint.
Do you install attic fans, and will one cool the house down?
We fit both kinds, electric and solar. A fan works on the attic rather than on the rooms below. It pulls hot air out of the attic, and whether you feel that downstairs depends on how well the ceiling underneath is insulated and sealed. We do not promise a temperature drop or a lower bill, and we would be careful of anyone who does.
And it only works at all if enough outside air can get in low at the soffits to replace what is leaving. On an attic with blocked or missing intake, a powerful fan pulls the easiest air it can find, which is conditioned air coming up through the ceiling from your rooms. That is why we look at the intake before recommending one.
Do you cover all of Dallas?
Yes, the whole city, and the county around it. Wherever the house sits, the evaluation is free and works the same way.
