Newcastle is one of the smallest cities we serve and one of the ones we know best. Our home base sits about four miles south down Coal Creek Parkway in Renton, which means a Newcastle job is a ten-minute drive rather than a cross-county trek. That proximity is the whole reason we can hold same-week openings here, send the same crew every single visit, and have Jack himself walk a house before quoting it.
Much of Newcastle climbs the western slope of Cougar Mountain, and the housing stock reflects it: three-level homes, tall two-story entryways, long stairwells, and big west-facing windows pointed at Lake Washington, Seattle, and the Olympics. These houses are genuinely harder to clean well than a single-story rambler, and it shows when a crew cuts corners — dust on the upper stair rails, smudges above eye level on the glass, vacuum lines that stop where the stairs start. We bring extension tools, lightweight stair vacuums, and enough crew hours to finish the whole house rather than the easy two-thirds of it. Interior window and glass-door cleaning is our most-requested add-on in Newcastle for exactly this reason.
The heart of the city around Lake Boren Park and the Newcastle Way / Coal Creek Parkway junction mixes single-family homes with townhomes and condominium communities. Townhome and condo cleaning is a different job from a detached house: shared entries, tighter footprints, HOA scheduling windows, and neighbors on the other side of the wall. We work quietly, park where we are supposed to, and can coordinate directly with an HOA or property manager when that is what the building requires.
The neighborhoods around The Golf Club at Newcastle and the Coal Creek corridor include some of the city's larger and newer properties. Homes at this size usually do better on a bi-weekly rhythm with an annual or semi-annual deep clean rather than trying to force everything into one marathon visit. We are happy to build that schedule with you, and to quote the deep-clean portion separately so there are no surprises.
Southern Newcastle blends into the Renton Highlands and Kennydale, and the 98056 and 98059 ZIP codes straddle both cities — which is precisely why so many Newcastle residents end up on the phone with a company that turns out to be based an hour away. We are not. Newcastle and Renton have been on the same route sheet for us since 2004. Newcastle also sits beside the Coal Creek Natural Area and Cougar Mountain Regional Wildland Park, and a lot of our clients here ask specifically for low-impact, non-toxic products. That has been our default for years.
Always on time! Very personable and efficient. Great workers and always the same 3 people. The best cleaners I have ever used!
Jack and his crew are fantastic! Always punctual, professional, and clean better than anyone I have used — close to 30 years.
Jack always sends a text the day before with arrival time. He cleans with his crew and they make your house sparkle like brand new!

Small-footprint offices, dental and medical practices, and retail suites along Coal Creek Parkway. Custom schedules, owner-supervised crews, full insurance coverage.
Newcastle's commercial base is compact by design — professional offices, dental and medical practices, salons, and retail suites clustered around Newcastle Commons and the Coal Creek Parkway corridor, plus HOA common areas and clubhouses. These are the accounts national janitorial chains treat as too small to service properly, and they are exactly the accounts we do well.
Every commercial account starts with a free walkthrough where Jack assesses scope, frequency, and any specialty requirements, then provides a written quote within 48 hours. Schedules typically run nightly after business hours, weekly, or bi-weekly. We match products to the space: hospital-grade disinfectants for medical and dental practices, food-safe products for breakrooms, and standard commercial-grade solutions elsewhere. Crews carry full liability insurance and bonding, and we provide documentation for your facility manager, HOA board, or property management company on request.
What you get that a chain will not give you: Jack's direct cell phone, the same crew every visit, and a company whose reputation in this corner of King County was built one account at a time over 20 years.
Free phone estimates — Jack will give you a real number in five minutes, not a range designed to be revised upward later.
Most Newcastle homes fall in this range. Because so much of the city is built on the hillside, layout matters as much as square footage — a three-level home with long stairwells takes longer than a same-size rambler. Larger properties, deep cleans, and move-out services are quoted separately. No hidden fees, no first-visit surcharge you find out about afterward.
A typical Newcastle residential clean runs $150 to $275 per visit. Newcastle homes tend to be larger than the King County average, and multi-level hillside layouts with finished lower floors take longer than a single-story rambler, so square footage and layout both matter. Deep cleans and move-out services are quoted separately. Jack gives free, honest estimates by phone in under five minutes — call (425) 445-0077.
All of them. We clean homes throughout Olympus, Lake Boren, China Creek, Coal Creek, Hazelwood, May Creek, the Highlands at Newcastle, the Cougar Mountain slopes, and the Newcastle Way and Coal Creek Parkway corridors. We also serve the adjacent Newport Hills and Somerset areas on the Bellevue side.
Yes. Ultimate Cleaning Service is based in Renton, about four miles and ten minutes from Newcastle City Hall, and we have cleaned Newcastle homes since the company started in 2004. That proximity is why we can offer same-week scheduling here and why Jack can personally stop by for a walkthrough rather than sending a call-center estimate.
Regularly. Much of Newcastle sits on the western slope of Cougar Mountain, so homes here often have three levels, tall stairwells, and large view-facing windows. We bring extension tools and lightweight vacuums for stairs, and interior window and glass-door cleaning is our most-requested add-on in this city.
Yes. We use eco-friendly, non-toxic cleaning products that are safe for children, pets, and indoor air quality. Newcastle borders the Coal Creek Natural Area and Cougar Mountain Regional Wildland Park, and many of our clients here specifically ask for low-impact products. Fragrance-free and specific-brand requests are no problem.
Yes, for both homeowners preparing a house for listing and tenants trying to recover a deposit. We deep clean every appliance, cabinet, drawer, baseboard, light fixture, and bathroom fixture, plus interior windows and window tracks. Book move-out work as early as you can — these appointments are time-sensitive and fill quickly.
Yes. Once your recurring schedule is set, the same crew comes every visit and learns your home, your preferences, and which products you want used. Jack supervises the work himself — you are not handed off to a rotating roster of strangers.
Yes. Newcastle's commercial footprint is small — mostly professional, dental, and medical offices along Coal Creek Parkway and around Newcastle Commons — and that suits us well. We handle nightly, weekly, and bi-weekly janitorial schedules with hospital-grade disinfectants where required, full liability insurance and bonding, and documentation for your property manager on request.
Yes — fully licensed, bonded, and insured with comprehensive liability coverage, and we carry all required Washington State business credentials. Documentation is available on request before your first clean.
