Insulation contractor in Spanish Springs, NV - attics that do their job
Complete Sparks Insulation Services is an insulation contractor based in Sparks, NV, working in Spanish Springs homes. We close up air gaps, insulate attics, walls and crawl spaces, and clear out old insulation that's stopped working.

Spanish Springs as we see it on the job
Spanish Springs fills its own valley along the northern edge of Sparks, so it's a short drive from where we're based. Most of the homes we go into here are in subdivisions, where a whole street shares a few floor plans, with the garage up front and a room or two built over it.
That sameness helps, because once I've been in one attic on a street I usually know where the hatch is, where the ducts run and which corner tends to get missed. It doesn't mean the attics match, though. One house still has the fill it was built with, untouched, and the next has a cable installer's path dug right through it, so I go up and look at every one before saying what it needs.
Permits, licenses and pricing for Spanish Springs jobs
Washoe County plans for the Spanish Springs community, and the county's building office issues building permits for any project that isn't on its exempt list. Before work starts, I check with the office for your address, tell you what it asks for and take care of the permit when your job needs one, and when it does, the permit is usually what the start date waits on. You can check two things about us or anyone else who bids. The Nevada State Contractors Board requires a contractor to be licensed before bidding or even talking price, and the county requires a county business license for businesses that come into unincorporated Washoe County to work.
We're fully licensed and insured. The price on a job here mostly follows the size of the attic, how many inches are already up there, whether old material has to come out and how many gaps need sealing, and the schedule turns on the permit, if there is one, and on anything that has to be fixed first, like a roof leak or old wiring. I give you your own number after I've seen the house. We do the same work in Cold Springs and Sun Valley, so if you've got family out that way, the same crew can help them too.
What we find in Spanish Springs attics
A lot of the houses here still have the blown-in insulation they were built with, which is loose fill blown through a hose, and by now it's settled, thin at the edges and pushed aside wherever someone crawled to a light or a vent. The room over the garage is the usual complaint, and the cause is often gaps around can lights, pipes and the attic hatch letting air slip right past the insulation. So we start with air sealing, closing those gaps before adding anything, then bring the edges up to the same depth as the middle and keep the eave vents clear so the attic can still breathe. Before we seal anything, I check the gas furnace and water heater and make sure the house still gets fresh air, because a tighter house changes how those appliances draw air.
Spray foam costs more and seals the air while it insulates, so it earns its price when your ductwork runs through the attic. For most attics here, sealing the gaps and topping up the loose fill does the job for less, and when the whole house feels uneven, our home insulation work looks at the walls and crawl space too.

I look at the house
I do the estimate in person, going up into the attic and the crawl space if there is one. It helps to clear the way to the attic hatch, since here it's often in a closet or the garage ceiling.
Go over what comes first
I show you how many inches are already up there and anything that should be handled before insulation, like a roof leak or old wiring. If insulation won't do its job yet, I'll tell you so.
Sort out permit and prep
We check with the office for your address and take care of the permit when the job needs one, and its review sets the start date. On install day we cover the path to the attic and protect your floors.
Install, then walk it together
Our small crew does the install, sealing gaps first and then insulating, and I'm on the job with them. Before we pack up, we walk the finished job with you, and it's backed by our satisfaction guarantee.
What good insulation work looks like
Spanish Springs insulation questions
How much does attic insulation cost in Spanish Springs?
Your price comes from your own attic, mainly its size, the depth already up there, how many gaps need sealing and whether anything has to come out first. Pulling out soaked or dirty insulation adds a full step to the job, and choosing spray foam over sealing and loose fill raises the cost too. I'll give you your number once I've been up there.
Can you blow new insulation over the old insulation in my Spanish Springs attic?
Usually yes, if the old insulation is dry and clean, and we measure how many inches are there before adding any. If it's been soaked or is full of droppings, it has to come out first, because new material on top just buries the problem.
How long does insulation take, and do we have to leave the house?
For air sealing and blown-in insulation you can usually stay home while we work, and how long we're up there mostly follows the attic's size and whether old material comes out first. Spray foam is different, because the foam maker sets a re-entry time, the wait before you, the kids and the pets can come back inside. We tell you that time before the job is booked so you can plan around it.
Should I fix a roof leak before adding attic insulation?
Yes, fix the leak first, because wet insulation stops slowing heat and keeps the wood under it damp. Washoe County doesn't require a permit for roof repair under 100 square feet or work done under the roof's one-year warranty, while inside Sparks city limits the city lists roofing as needing a permit. I'll point out any stains or soft spots I find so you can get the roof handled before we insulate.
What causes damage in crawl spaces in Spanish Springs?
Moisture and pests are the usual causes, and Washoe County's design requirements rate termite damage risk here as moderate to heavy. That's why we look over the wood for termite signs and soft spots before putting down insulation or a vapor barrier, since covering damage only hides it. If we find any, I'll tell you to get it treated first.
What is the best way to fix a hot room over the garage?
Usually the fix is sealing the gaps around that room and filling the spaces beside and under it, where the insulation is often thin or missing. In a lot of the houses here those spots are hard to reach, so I check them from the attic and the garage before deciding whether loose fill or foam makes more sense.
