The Complete Home Insulation Solution: Attic, Basement, Crawl Space, Walls and Air Sealing
DBS Repair does not patch insulation problems with a layer of fiberglass and call it done. We deliver a complete, area-by-area insulation system using waterproof, high-performance materials built for the Minnesota and Wisconsin climate, always paired with professional air sealing to eliminate the energy losses that standard insulation alone cannot fix.
Step 1: Attic Insulation and Air Sealing
— Stopping Heat Loss at the Top of Your Home
The attic is where most homes lose the most heat. Every upgrade DBS Repair installs starts with thorough air sealing to close the gaps that let conditioned air escape, then adds the right insulation system for how the attic is used.
For standard attics:
- Airtight vent covers block cold winter air and humid summer air from entering the crawl space
- A heavy-duty vapor barrier is installed across floors and walls to stop moisture vapor transmission completely
- Concrete block walls receive a mechanically attached wall covering that seals open cavities while keeping the space visible for pest inspections
- The result is a clean, dry, conditioned environment, not an open underground chamber
For attics used for storage or housing HVAC equipment:
- DBS Repair installs the SuperAttic System, which insulates directly beneath the roof rafters rather than the attic floor
- SilverGlo rigid foam panels create an airtight, continuous insulation layer with a built-in radiant heat barrier
- The result is a conditioned attic space that stays usable year-round without allowing outside air to enter
Step 2: Basement Insulation
— Turning a Cold, Damp Space Into a Comfortable One
Basements demand insulation materials that can handle moisture without degrading. DBS Repair replaces failure-prone fiberglass batts with rigid foam systems specifically engineered for below-grade environments.
For basement walls:
- Rigid foam wall panels will not compress, fall out of place, or absorb moisture the way fiberglass batts do
- Basement to Beautiful wall insulation panels are sized specifically for basements and include built-in wiring channels and steel flanges ready for drywall
- The system prepares the entire wall surface for finishing in one step, saving time and reducing the total project cost
For basement floors:
- ThermalDry Insulated Floor Decking addresses the discomfort of cold, concrete basement floors with a complete thermal barrier
- Interlocking panels combine high-performance rigid foam insulation with an inorganic composite subfloor surface
- The system will never support mold or wood rot and creates a finished floor surface ready for carpet, laminate, or tile
Step 3: Crawl Space Insulation
— Waterproof Solutions for the Most Moisture-Prone Area of Your Home
Some of the most impactful Home Insulation Solutions, including Crawl Space Insulation, happen in places you cannot easily see. Finished wall cavities, basement rim joists, crawl spaces, and floors above attached garages are consistently under-insulated and require specialized materials and installation techniques to fix properly.
For crawl space walls:
- SilverGlo Crawl Space Wall Insulation uses expanded polystyrene foam infused with graphite particles that boost insulating ability by 24 percent
- Closed-cell construction means zero moisture absorption and zero degradation over time
- A built-in radiant heat barrier on the visible face reflects warmth back into the crawl space
For crawl space floors:
- TerraBlock crawl space insulation provides a 3/4-inch foam layer covered on both sides with a durable moisture barrier
- Creates a cushioned, puncture-resistant surface that handles regular foot traffic without compressing or degrading
- Delivers critical thermal protection on rough or uneven dirt floors where standard insulation cannot be installed
Step 4: Spray Foam and Dense-Pack Cellulose for Walls, Rim Joists, and Floors Above Garages
Some of the most impactful Home Insulation Solutions for improving energy efficiency happen in places you cannot easily see. Finished wall cavities, basement rim joists, and floors above attached garages are consistently under-insulated and require specialized materials and installation techniques to fix properly.
- Two-part closed-cell polyurethane spray foam expands to completely fill irregular cavities, acting as both a high-R thermal barrier and an airtight air barrier simultaneously
- Spray foam is waterproof, does not support mold growth, and bonds to framing to add structural rigidity as a secondary benefit
- Dense-pack cellulose is injected directly into finished wall cavities through small access points, eliminating voids without requiring demolition
- Rim joists receive spray foam treatment to address one of the single largest sources of air leakage and heat loss in the entire home
- Floors above attached garages get complete insulation coverage between the joists, eliminating the cold floor problem in the living space above

Why Every DBS Repair Insulation Job Includes Air Sealing:
The Step Most Contractors Skip
Adding insulation without air sealing is like stuffing a sweater with cotton and leaving all the zippers open. DBS Repair treats every insulation upgrade as a whole-home thermal system, not a single-area fix. Air sealing is always part of the work.
- Air sealing closes the gaps, holes, and cracks where conditioned air leaks out and cold outside air seeps in
- Without it, the stack effect continuously pumps heated air out through the attic and pulls cold air in through lower-level gaps
- Insulation slows heat transfer but does nothing to stop air movement through gaps. Air sealing handles what insulation cannot
- The combination of air sealing and correctly rated insulation is what produces the dramatic energy bill reductions homeowners expect
- DBS Repair performs a full air sealing assessment as part of every insulation project to identify and close every significant leakage point

Is Your Home Losing Heat? DBS repair Fixes Insulation Problems That Cost You Money Every Month
Most homes in Minnesota and Wisconsin are significantly under-insulated. Whether it is your attic, crawl space, basement, or walls, gaps in your insulation system mean your heating and cooling equipment works harder than it should. DBS Repair delivers permanent insulation upgrades that lower your energy bills and make every room in your home more comfortable.
Most Attics Are Severely Under-Insulated and It Is Costing You on Every Energy Bill
The U.S. Department of Energy recommends R-49 to R-60 insulation for attics in northern climates like Minnesota and Wisconsin. Most existing homes fall far short of that standard, and the gap between what you have and what you need shows up directly on your utility bills.
- Many older homes have as little as R-19 in the attic, roughly one third of the recommended level for northern climates
- Heat moves naturally from warm to cool spaces, so an under-insulated attic bleeds warmth out of your home around the clock
- Heating and cooling systems work 25 to 40 percent harder when attic insulation is insufficient, driving up monthly energy costs
- Adding the right amount of attic insulation is one of the highest-return home performance upgrades available to homeowners
- DBS Repair performs a full insulation assessment to measure your current R-value and recommend the right solution for your home

Insulation Alone Will Not Stop Cold Drafts:
Why Air Sealing Is Just as Important
One of the most common and costly misconceptions in home performance is that adding more insulation will eliminate cold drafts. It will not. Insulation slows heat transfer but does nothing to block air movement. Without air sealing, your home is still leaking conditioned air every hour of the day.
- Gaps around plumbing penetrations, electrical wires, and recessed lights allow warm interior air to escape into the attic constantly
- The “stack effect” occurs when rising warm air escapes through the attic and pulls cold outside air in through gaps in lower levels of the home
- This continuous air exchange forces your HVAC system to condition far more outside air than it is designed to handle
- Air sealing those gaps before installing new insulation is the only way to fully eliminate drafts and stabilize indoor temperatures
- DBS Repair combines professional air sealing with insulation installation so your home performs as a complete thermal system
Moisture Is Destroying Your Existing Insulation From the Inside Out
Standard fiberglass batt insulation is highly vulnerable to moisture. Once it gets wet, it loses its insulating ability, becomes a breeding ground for mold, and eventually falls apart. If your home has fiberglass insulation in the attic or crawl space, there is a good chance moisture has already compromised it.
- Warm, humid air from bathrooms, kitchens, and living spaces leaks into the attic where it condenses on cold surfaces
- Crawl spaces naturally draw in ground moisture, which condenses as humid air cools against cold surfaces and framing
- Fiberglass insulation absorbs moisture like a sponge, compresses under the added weight, and loses its R-value rapidly
- Wet, heavy insulation eventually falls from attic ceilings and crawl space floors in useless piles, leaving areas completely unprotected
- Moisture-damaged insulation creates the ideal damp environment for mold growth and accelerates wood rot in structural framing
- DBS Repair replaces failed fiberglass with waterproof, moisture-resistant alternatives engineered for the Minnesota and Wisconsin climate
Cold Floors, Hot Spots, and Drafty Rooms:
The Hidden Insulation Gaps Most Contractors Miss
Insulation problems are not always obvious. Some of the most impactful heat loss in a home happens in areas that are easy to overlook during construction or renovation. If you have rooms that never quite reach a comfortable temperature, these are the most likely culprits.
- Floors above uninsulated attached garages or cantilevered overhangs are a leading cause of persistently cold rooms in the living space above
- Basement rim joists are one of the most significant sources of air leakage and heat loss in a home and are almost always under-addressed
- Leaving just 5 percent of a wall or ceiling cavity uninsulated can reduce that area’s total insulation performance by up to 50 percent
- Electrical wires and outlets in exterior walls compress fiberglass batts and create voids that eliminate insulation value in those spots
- Finished walls with missing or compressed insulation require specialized retrofit solutions that go beyond what standard batts can provide
- DBS Repair inspects every critical area including rim joists, garage ceilings, cantilevered floors, and wall cavities to ensure complete thermal coverage
