Reliable Merced Spray Foam Insulation is an insulation contractor working in Delhi, CA. We air seal and insulate attics, walls and crawl spaces, from older houses with thin, settled fill to rooms over the garage that never cool down.
Delhi sits northwest across the Merced River from Livingston, a short drive up from us in Merced. On jobs here we see older single-story houses, newer homes in the subdivisions, and houses out on farm parcels at the edge of Delhi. The calls are mostly about rooms that never feel right: a back bedroom that stays hot, cold floors, a room over the garage nobody wants to use.
The older houses usually have a few inches of settled fill up top and a crawl space underneath. I go up with a flashlight and down under the floor on the same visit, because insulation laid over a leak or a soaked patch is money wasted.
Spray foam insulation seals and insulates in one pass, so we use it where loose fill can't stay put, like sloped ceilings and rim joists.
Explore serviceMost Delhi calls start with attic insulation, bringing thin, settled fill up to an even depth so the edges end up as deep as the middle.
Explore serviceBlown-in insulation, loose fill blown through a hose, is usually the best value for topping up an older attic.
Explore serviceWhen the whole house feels off, home insulation starts with a look at the attic, walls and crawl space so we fix them in the right order.
Explore serviceWhen old fill is soaked or full of droppings, insulation removal comes first, because new material laid over it keeps the problem in the house.
Explore serviceFor cold floors over a crawl space, crawl space insulation goes between the floor joists once we've checked that the ground below is dry.
Explore serviceSome older houses here have empty or slumped walls, and wall insulation can be blown in through small holes we patch afterward.
Explore serviceAir sealing services close the gaps around pipes, wires, can lights and the attic hatch, which is where a drafty house usually loses the most.
Explore serviceWhere a house has a basement or a below-grade room, basement insulation on the walls takes the chill out of the space.
Explore serviceClosed-cell foam insulation, a dense foam that also blocks moisture, suits damp spots like crawl space walls.
Explore serviceOpen-cell foam insulation is lighter and softer, and it works well on a roof deck or in walls where moisture isn't the issue.
Explore serviceProperty managers call us for commercial insulation in shops and offices, and we schedule the work around the hours people are inside.
Explore serviceA crawl space vapor barrier covers the dirt under the house so ground moisture stays out of the joists and the insulation.
Explore serviceWith vapor barrier installation, which side of the wall or floor it goes on matters more than the material, so we place it for your house.
Explore serviceAttic air sealing is the step crews skip most often, so we seal the attic floor before anything gets blown over it.
Explore serviceRetrofit insulation adds to what an older house already has without tearing out finished walls or ceilings.
Explore serviceMerced County serves Delhi, so for an address in the unincorporated area the county's Building and Safety Division issues building permits. Every building permit there also goes through county planning review, so a job that needs one has that review built into its schedule. We check whether your address falls under the county or a city, and if the work needs a permit, we take care of it and set up the inspection. Any business working in unincorporated Merced County needs a county business license, and you can check a contractor's with the status check on the county permit portal.
The price moves with what's already in your attic and what has to happen before anything new goes in: how many inches are up there, whether old fill has to come out, how many gaps need sealing, how tight the crawl room is, and foam or loose fill. The schedule turns on that same prep and on any permit review. We do this work all over this side of the county, out in McSwain and up toward Turlock, and I write each estimate after I've been up in the attic, so the number comes from your house.
Tell us which room never feels right, or what you've noticed in the attic or crawl space. We reply within one business day to set a time, and I come out myself, look things over with a flashlight, take photos and write the estimate. It's free, and there's no obligation to go ahead.
(209) 308-1021Usually not, unless your ductwork runs through the attic. Foam costs more because it seals air while it insulates, but in most attics, sealing the gaps first and then topping up with blown-in fill does the job for less. When the ducts are up there, foam on the underside of the roof keeps them inside the insulated space, and that's when I'll recommend it.
A straight top-up over sound insulation goes quicker than most people expect, and the time grows when old fill has to come out or there's a lot of sealing to do first. I'll walk you through the plan for your house at the estimate, and I check the work before we call it done and pack up clean.
Yes, you, your kids and your pets stay out until the re-entry time, the point when it's safe to come back inside. We'll give you that time before we start so you can plan the day. Blown-in insulation and air sealing usually don't need anyone to leave.
We're based in Merced and work in many cities around it, north toward Modesto and south toward Madera. These are the ones with their own page, so if yours isn't listed, call and ask.
I'd sooner tell you a top-up isn't worth the money than sell you one, so call (209) 308-1021 or send the form and find out what your attic actually needs.
If there's a room in your Delhi house that never feels right, tell us about it and we'll take it from there.
