Ty and his crew did an outstanding job. Fast, Thorough and very careful to not disturb any of the trees or greenery that didn’t need to be disturbed. I considered the Price fair for the work they did or better yet for the work I didn’t have to do. As I need further work done around the place I’ll be contacting Ty for sure! Thanks, Ty you and your guys are a credit to the small business Community!

Ty and Alan were fantastic to work with. Very fair pricing and they gave me a quote within an hour and then picked up our trash the next day. They were great communicators, and efficient and nice when they arrived. They swept the driveway where we had garbage stored and left all very nice. They even took some dead branches that were not part of the quote and also helped me move a heavy piece of slate into my garage!! I would give them 5 plus stars and would use them again without hesitation.

We were very impressed with the two young men that came and removed a lot of junk from our barn in a short time. I would definitely recommend using 303 Demolition & Junk removal.

drywall removal during a Boulder tear-out
Drywall and Plaster

Is Drywall Removal Part of a Boulder Tear-Out?

Yes, and in Boulder it is the most common piece of the job.

Pulling drywall opens access to plumbing, wiring, and insulation, and leaves a clean surface for new framing or finishes. We remove it carefully so the framing and utility runs behind it stay intact, then bag and haul every piece out with the same crew.

Older Boulder housing stock makes this trickier than people expect. Plenty of homes near University Hill and the Whittier blocks were built before the 1950s, so you get plaster over wood lath instead of drywall. That comes down heavy, dusty, and slow. It is a different job than a 2005 build and we plan for it before we show up.

Drywall removal is usually one part of a bigger project. It shows up in kitchen demolition and bathroom demolition work, and we coordinate around your other trades.

When to Call

When Do Boulder Homeowners Need a Tear-Out Crew?

Most people do not call on day one. They call on day three, when the trash bags are stacked by the door and the dumpster is already full.

  • Plaster and lath, not drywall

    Common in pre-1950s Boulder homes. Heavy, dusty, and slow to bring down.

  • Tile set in a mortar bed

    If the tile will not pop loose there is a concrete layer under it. Different tool, different weight class.

  • More than one room at once

    Debris piles up faster than one person can carry it out.

  • A tight timeline

    If framing starts Monday, the tear-out cannot drag into next week.

  • Stairs, no driveway, shared alley

    In older neighborhoods, getting debris out of the building is half the job.

  • The surprises start

    Old wiring stapled inside a wall. A hidden pipe run. Soft subfloor. The pace drops and the pile grows.

Demolition is not hard because of the swinging. It is hard because of what is left on the floor afterward. A single kitchen tear-out can fill a pickup four or five times over, and that is before the cabinets.

Before You Book

When Should You Skip the Crew and Do It Yourself?

Skip us when you can get the debris off your property yourself.

One small bathroom’s worth of vinyl flooring, a single vanity, a closet shelf system, a laminate countertop. Those come out with hand tools and fit in a pickup bed. Hiring anyone for that is spending money you do not need to spend.

Timing matters too. If your contractor has not pulled permits and the cabinets are still on order, do not rush the demo. An open wall sitting for six weeks is a hole collecting dust, and Boulder winters run dry and cold. An exposed exterior wall bleeds heat fast. Wait until the next trade is ready to walk in.

The honest test: can you get the debris out of the house and off your property by yourself? If yes, swing away. If the answer is a pile in the driveway with no plan, that is when a crew earns its keep.
Doing It Right

What Goes Wrong When a Tear-Out Is Rushed?

Damaged plumbing lines, cut wiring, and weakened structural supports, mostly. Every one of those turns a demo saving into a repair bill.

  • Load-bearing walls

    Identified before the first wall comes down. We will say straight out if your contractor or an engineer has to weigh in first.

  • Live wiring and gas lines

    We do not touch either without a plan. Utility runs get mapped before anything gets opened.

  • Anything needing a permit

    Flagged up front rather than discovered on demo day, when it costs you a week.

We identify load-bearing walls, utility runs, and anything that has to stay before work starts, then protect the parts of the house that are not part of the job.

Permits and Older Homes

Do You Need a Permit to Gut a Room in Boulder?

It depends on what is coming out and how much of it.

Cabinets, fixtures, and non-load-bearing walls are a different question from anything structural. What surprises most Boulder homeowners is the asbestos rule. The City of Boulder and CDPHE require a certified asbestos inspection for any structure regardless of age once the project passes the trigger levels.

  • 32 square feet of surfacing material such as drywall or flooring
  • 50 linear feet of pipe insulation
  • The equivalent of a 55-gallon drum of waste

A single room of flooring can cross that line. Structures over 50 years old carry a separate consideration in the City of Boulder, so anything in the older neighborhoods is worth checking early rather than on demo day.

Where the inspection sits

The inspection and any abatement are handled by state-certified specialists, not by a demolition crew. We flag when your project looks likely to cross a trigger level so it does not stall your schedule.

The CDPHE Asbestos Compliance Assistance Group can be reached at 303-692-3100.

Pricing

How Is a Boulder Tear-Out Priced?

Either a flat price for a defined scope, or by the volume of debris hauled out. The tear-out is often the cheap half. Hauling and dumping is where the money goes.

  • Material weight

    Concrete, mortar-bed tile, and old lath and plaster cost more to haul than drywall or carpet.

  • Access

    A third-floor Boulder condo walk-up means every load goes down stairs by hand.

  • Age of the home

    Older Boulder houses often have plaster over lath and layered flooring stacked on top of each other.

  • Selective versus full tear-out

    Saving cabinets or trim takes hand work and time. A full gut moves faster per square foot.

Landfills and transfer stations charge by weight. A small bathroom can outweigh a large room of drywall, so the disposal bill follows the scale, not the square footage. That is why a tile shower quote and a drywall wall quote look so different.

Homeowners often bundle flooring removal into the same visit. One mobilization, one bill.

Ask three things of anyone you call. Is debris removal in the price or added after? Who pays the dump fees? What happens if there is more behind the wall than expected?

FAQ

Frequently Asked Questions About Interior Demolition in Boulder, CO

How long does interior demolition take in Boulder?

A single kitchen or bathroom tear-out usually wraps in one to two days.

Older Boulder homes near University Hill with plaster and lath take longer than newer builds, since that material comes down heavier and dustier.

Timelines stretch with multiple rooms, tile set in a mortar bed, or surprises like old wiring behind a wall. We walk the space first so you know before we start.

Do I need a permit for interior demolition in Boulder?

It depends on scope. Cabinets, fixtures, and non-load-bearing walls are different from structural work.

The rule that catches people is asbestos. Boulder requires a certified inspection for any structure, regardless of age, once the project passes 32 square feet of surfacing material or 50 linear feet of pipe insulation.

We flag it up front rather than guessing.

What happens to the debris after demolition?

It leaves with us the same visit.

A single kitchen demo can fill a truck bed several times over with cabinets, tile, and broken counter, and we do not leave that in your driveway.

Tear-out and haul-off are one job with the same crew, so you are not renting a dumpster or calling a second company on Monday.

Can I do interior demolition myself?

Small jobs, yes. One bathroom's vinyl floor, a single vanity, or a closet shelf system works with hand tools and a pickup.

Bigger jobs are different. Plaster comes down in heavy chunks, and mortar-bed tile can weigh several hundred pounds per room.

If the debris pile is more than you can haul, a crew saves you the time and the dump runs.

Why do older Boulder homes take longer to demo?

Plenty of homes near University Hill were built before the 1950s, so they have plaster over wood lath instead of drywall.

That material comes down heavier, dustier, and slower. Old mortar-bed tile adds weight.

We plan for it before we show up so the job does not stall when we open a wall.

Should I wait to start demo if my contractor is not ready?

Yes. Hold off if permits are not pulled or materials have not arrived.

An open wall sitting for weeks collects dust, and in Boulder's dry, cold winters an exposed exterior wall bleeds heat fast.

Better to time the tear-out so the next trade walks in right after.

Do you protect the parts of the house that are staying?

Yes. We tape plastic over doorways, cover floors we are keeping, and control dust while we work.

We identify load-bearing walls, wiring, and plumbing runs before anything comes down.

Do you remove flooring during an interior tear-out?

Yes, down to the subfloor if that is what the plan calls for. Carpet, vinyl, laminate, hardwood, and tile all come out.

Tile set in a mortar bed is heavier and slower than the rest, so we account for it in the quote.
