Houlton: The County Seat at the Top of I-95

Where Maine Meets the Border

Houlton holds a unique place in Aroostook County. It's the County seat — home to the courthouse, county offices, and the regional government infrastructure. It's the terminus of I-95, where the longest highway in the eastern United States finally runs out of road. And it's one of the busiest border crossings between the U.S. and Canada, with steady cross-border commerce and traffic running through downtown every day of the year.


That mix — government, commerce, residential, and border-town energy — gives Houlton a different feel than anywhere else in The County. It also creates a wide range of exterior cleaning needs: historic brick storefronts in Market Square, professional office buildings, courthouse and county facilities, hotels and travel-related businesses, and residential properties from older Victorians near downtown to newer construction out toward the surrounding towns.


We work across all of it.

Services in Houlton

Full Service from the Same Local Company

Every Clean Slate service is available to Houlton property owners:

Soft Washing

Low-pressure cleaning for siding, painted surfaces, and historic building exteriors. Removes algae, mildew, and biological growth without damaging delicate materials — especially important on the older brick and wood construction common in downtown Houlton.

Pressure Washing

Driveways, walkways, parking lots, sidewalks, and concrete surfaces. After a Houlton winter, every concrete surface is overdue.

Professional Window Cleaning

Storefronts in Market Square, professional offices, hotels, retail businesses, and homes. Streak-free results, inside and out.

Gutter Cleaning

Critical fall service. Clogged gutters going into winter cause ice dams, foundation damage, and the kind of repair bills that hit hardest in spring.

Roof Washing

Safe soft-wash cleaning that removes black streaks, moss, and algae from asphalt shingles. The right method for any roof — pressure washing destroys shingles.

Wood Restoration & Renewal

Decks, fences, wood siding, and outbuildings restored at a fraction of the cost of replacement. Especially relevant for the older homes around historic downtown Houlton, where original wood is often worth saving.

Stain & Oxidation Removal 

Rust streaks, tannin stains, vinyl oxidation, and the specialty marks most cleaning companies say can't be removed. Our niche specialty.

Serving Houlton from Madawaska

Honest About the Drive — and the Service

We'll be straight with you: Houlton is the southern edge of our service area, about two hours from our home base in Madawaska. That's a real drive, and we don't pretend otherwise.


What that means in practice:


  • Houlton is on a scheduled rotation, not a daily call-out. We batch Houlton work — usually grouping multiple jobs into a single trip to give you fair pricing and predictable scheduling. Same-week service is often available; same-day rarely is.
  • Commercial accounts on recurring schedules work best for properties this far south. If you're a Houlton business that wants regular window cleaning, monthly exterior washing, or quarterly building maintenance, we can build you a schedule that locks in the days and rates ahead of time.
  • For one-time residential work, book early. Spring books up fast across our whole service area, and the southern end of our territory is the first to fill up. Get on the calendar in March or April for May or June work.



What you get is the same quality and the same guarantee as customers anywhere else we work. We just want to be upfront about the logistics — because that's how we'd want to be told if we were the ones hiring.

Properties We Work On in Houlton

The Full Range of Houlton Properties

Houlton's mix of historic, commercial, and residential properties gives us a wide variety of work in the city:


  • Historic homes and downtown buildings - Older homes with original wood siding, brick storefronts in Market Square, and historic commercial buildings throughout downtown. These properties require the right methods — soft washing instead of high pressure, gentle restoration over aggressive cleaning.

  • Professional offices and legal practices - Law offices, accounting firms, and professional service businesses concentrated around the courthouse area. Recurring window cleaning and exterior maintenance.
  • Single-family homes - Established neighborhoods and newer developments throughout Houlton. Every roof, siding, and outdoor structure type common in southern Aroostook.
  • Properties in surrounding rural communities - Hodgdon, New Limerick, Linneus, Ludlow, Smyrna, Oakfield, and surrounding towns. Rural homes, farm properties, and outbuildings on the same scheduling rotation as Houlton-proper work.

Frequently Asked Questions


  • Do you actually serve Houlton, or is it on the edge of your area?

    Yes, we serve Houlton — though it's the southern edge of our regular service area. We schedule Houlton work in batches, usually grouping multiple jobs into a single trip. Same-week service is often available; same-day rarely is. We're honest about the logistics rather than promising what we can't deliver.

  • How much extra does it cost to have you come to Houlton?

    Less than you'd think. We batch trips to keep travel overhead reasonable, and our pricing reflects the actual work — not the windshield time. The veteran and returning customer discount also applies in Houlton.

  • Do you do commercial work for Houlton businesses?

    Yes. Commercial accounts on recurring schedules actually work best in Houlton — predictable trips, fair pricing, and locked-in scheduling. We work with hotels, restaurants, retail businesses, professional offices, and government facilities.

  • Can you handle historic and older buildings carefully?

    Yes. Soft washing — low pressure with the right cleaning solutions — is specifically designed for older brick, wood, and painted surfaces that high pressure would damage. Most of downtown Houlton's historic buildings require this approach.

  • Do you serve the border crossing area commercial properties?

    Yes. Hotels, restaurants, gas stations, and businesses along I-95 and near the border. High-visibility properties that need to look professional year-round for steady traveling customer traffic.

  • What's the best time to book Houlton work?

    For spring work, get on the calendar in March or April. Spring books up fast across our service area, and Houlton is usually the first stretch to fill up. For fall gutter cleaning, book by August.

  • Do you offer the veteran discount in Houlton?

    Yes. 10% off any service for veterans, anywhere we work. Same discount for returning customers and friends or family of past customers.

  • Do you serve Patten, Sherman, or Island Falls?

    Yes. Those communities are in our southern service area along with Houlton. Same batched-scheduling approach — book early.
