Who moves into old Englewood houses?

Dense blocks, mature trees, and aging structures shape the guest list. What drives our Englewood exclusion work:

House mice through foundation-era gaps
Squirrels off the old canopy into fascia & soffits
Platte & Little Dry Creek field rodents, seasonal
Raccoons testing chimneys & porch roofs

The Brands Behind Every Grizzly Install

We don’t install mystery material. Every Arvada project uses products from the industry’s most trusted manufacturers.

01THE PROBLEM

A 1920s House Has 100 Years of Doors It Never Meant to Build.

Settled stone foundations, gapped siding corners, original vents with rusted screens, and balloon-framed walls that connect them all straight to the attic. Old construction hands wildlife an interstate. Exclusion on these houses is craftsmanship, and it is the only thing that ends the cycle.

AFoundations that gap a little more each decade

Stone and early-concrete walls open seams as they settle, and every seam is a mouse door. We close them with mortar-grade fills and steel, materials that age slower than the foundation does.

BThe canopy commute onto your roof

Englewood’s old silver maples put squirrels level with fascia boards all over Bates-Logan and Romans Park. Once through a soffit corner, they treat balloon-framed walls as elevators. Metal flashing at the entry points ends the commute.

CWalls that deliver guests to every floor

Open balloon framing means a mouse entering at the sill can exit into the attic, or your kitchen wall. Capping cavities and sealing the sill line breaks the internal highway old framing built.

DDroppings a century in the making

Attics and cellars that hosted generations of rodents hold serious contamination, and Colorado deer mice make disturbance a health risk. HEPA equipment and respirators are the standard, not the upgrade.

02THE FIX

Steel the Openings. Clear the History. Deter the Future.

Traps manage a symptom. On old houses the cure is construction-grade: exclusion, remediation, and deterrent insulation from one crew.

03WHAT TO EXPECT

Every Gap Steeled. Every Trace Gone. On Paper.

An Englewood exclusion project, survey to certificate:

STEP 1 · PREP
The century survey

Foundation seams, siding corners, soffits, vents, and chimney caps, every era’s weak point gets checked and photographed into your entry map.

STEP 2 · REMOVAL
Generations of evidence, extracted

Nests, droppings, and soiled material leave through HEPA-filtered equipment under deer-mouse protocols. Cellars get the same treatment as attics.

STEP 3 · AIR SEALING
Exclusion built like masonry repair

Mortar-grade fills in the stone, steel mesh at vents, flashing at soffit corners and roof returns, chimney caps where the survey demands.

STEP 4 · INSTALLATION
Scent history erased

Antimicrobial treatment neutralizes decades of pheromone trails, the invisible signage that has advertised your house since before you owned it.

STEP 5 · QUALITY CHECK
TAP® in, certificate out

Borate-treated cellulose rebuilds the insulation, then a final pass on every sealed point with photos added to your records, and the guarantee behind it.

The Grizzly 100% Guarantee

If the work isn't right, we make it right. That's the reputation we've built across the Front Range, and it's our only sales pitch.

04COST & SAVINGS

What Rodent-Proofing Costs in Englewood

Old houses take more craft than tract homes, and honest pricing follows the survey, not a franchise sheet. Four drivers, itemized after a free inspection.

Era gap count

Foundation seams, soffits, vents, and chimney points

Intruder mix

Mice, squirrels, and raccoons need different steel

Contamination age

Generational buildup takes longer to clear safely

TAP scope

Spot rebuild or full deterrent blanket

Three ways the net cost drops

Rebates on the rebuild

TAP qualifies as insulation for Xcel rebate purposes, the deterrent layer pays like an efficiency upgrade.

Federal 25C tax credit

30% of qualifying insulation costs, up to $1,200 per year, under the Inflation Reduction Act.

Wiring & woodwork protected

Gnawed cloth-wrapped wiring in old walls is a genuine fire hazard, exclusion is cheap insurance against it.

"Squirrels had used our 1922 house near Romans Park for a decade, three companies, three failed patches. Grizzly flashed every soffit corner, steeled the foundation seams, and replaced the ruined insulation with TAP. Two years silent, guarantee still in the drawer."

05QUESTIONS

Rodent-Proofing in Englewood, Answered Straight

Prefer to just ask?

Call and talk to the crew that will actually be in your attic.

Age multiplies openings: settled foundations, dried-out siding joints, rusted vent screens, and balloon framing that turns one entry into whole-house access. Wildlife reads a 1920s block as habitat. Exclusion closes the century’s accumulated doors with materials that do not age out.

The survey sets it: era gap count, intruder mix, contamination age, and how much insulation needs the TAP rebuild. Old homes carry more entry points than new ones, and still, one thorough exclusion generally undercuts a few years of recurring pest contracts. Line items in writing first.

Yes, exclusion is eviction, not extermination. One-way doors let animals leave and not return, then flashing and steel close the architecture behind them. It is also the only approach that works long-term, because the next squirrel finds the same sealed corner.

Treat it as if yes. Colorado deer mice can carry hantavirus, and decades-old droppings aerosolize when swept or vacuumed with household gear. Our protocol, HEPA filtration, respirators, antimicrobial treatment, exists precisely for this material.

Most Englewood homes are surveyed, sealed, and cleaned inside two days; straightforward exclusions finish in one. Squirrel work sometimes adds a short one-way-door phase first, nothing gets sealed inside, ever.

Then the guarantee brings us back, and the fix is on us at a sealed point. In practice steel, flashing, and a scent-neutralized, TAP-insulated attic remove both access and incentive, which is why we can put the promise in writing.
