We provide a full range of exterior cleaning and maintenance services: pressure washing, soft washing, roof cleaning, gutter cleaning, window washing, patio and deck cleaning, driveway and walkway cleaning, moss prevention treatments, seal and stain applications, and commercial exterior cleaning. Each service is tailored to Portland’s specific climate conditions and the materials found on Pacific Northwest properties.

Yes. Every estimate is free with no obligation. We can provide quotes based on photos and property details you share, or we can schedule an on-site assessment for larger or more complex projects. Most estimates are returned within 24 hours of your inquiry.

Absolutely. Belovora Exterior Cleaning is fully licensed to operate in Oregon and carries comprehensive general liability insurance. We also use DEQ-compliant cleaning solutions, meaning our products and runoff practices meet Oregon Department of Environmental Quality standards.

We serve the greater Portland metro area including Portland, Beaverton, Lake Oswego, Tigard, Tualatin, Hillsboro, Gresham, Milwaukie, Oregon City, West Linn, Happy Valley, Clackamas, Wilsonville, and Sherwood. If your city is not listed, contact us — we may still be able to help.

You can request an appointment through our online contact form, call us directly at (503) 840-9589, or send us an email. We typically respond within a few hours during business days and will work with you to find a date and time that fits your schedule.

Pricing depends on the service type, property size, surface condition, and accessibility. A basic driveway pressure wash starts at a different price point than a full roof treatment. We provide transparent, itemized quotes so you know exactly what you are paying for before any work begins. No hidden fees, ever.

Yes. Many homeowners combine services for better value — for example, pairing a roof cleaning with gutter clearing, or bundling driveway washing with a patio and deck treatment. We offer customized packages based on your property’s needs and can suggest combinations that make sense for seasonal maintenance.

We accept all major credit cards, debit cards, checks, and digital payment methods. Payment is due upon completion of the work, after you have had a chance to inspect the results. For larger commercial projects, we can arrange milestone-based billing.

For substantial projects such as full-property treatments or commercial contracts, we can discuss flexible payment arrangements on a case-by-case basis. Contact us to talk through the options available for your specific project scope and budget.

Light rain typically does not affect our work — in fact, damp surfaces can improve the effectiveness of certain soft wash treatments. However, if heavy rain or storms are forecasted, we will proactively reach out to reschedule at no additional cost. We monitor Portland weather closely and plan accordingly.

Late spring through early fall (April to October) is the most popular window, but we work year-round. Fall is ideal for gutter cleaning before winter debris builds up. Spring is perfect for removing winter moss and algae. Summer is the best time for sealing and staining, since surfaces need dry conditions to cure properly.

During peak season (May through September), we recommend booking two to three weeks in advance. Off-season appointments can often be scheduled within a week. For commercial contracts or multi-service packages, earlier booking gives us the best flexibility to accommodate your timeline.

Most residential jobs are completed in two to five hours, depending on scope. A single driveway wash might take an hour, while a full house wash with roof treatment can take a full day. We provide time estimates with every quote so you can plan your day around the work.

Pressure washing uses high-pressure water to remove tough buildup from hard surfaces like concrete, brick, and stone. Soft washing uses lower pressure combined with specialized cleaning solutions to safely clean delicate surfaces such as roofing, vinyl siding, stucco, and painted wood. We assess every surface and choose the method that delivers the best results without risk of damage.

Not when done correctly. Damage typically results from using too much pressure on the wrong surface. Our technicians are trained to match PSI levels and nozzle types to each material. We never use high-pressure methods on surfaces that require a gentler approach — that is exactly what soft washing is designed for.

We use professional-grade, DEQ-compliant cleaning agents that are biodegradable and specifically formulated for each type of surface contamination — whether it is moss, algae, mildew, oil stains, or oxidation. Our solutions break down organic growth at the root level rather than just removing the surface layer.

Yes. We use eco-friendly, biodegradable solutions and take precautions to protect your landscaping during every job. We pre-wet surrounding plants, cover sensitive vegetation when needed, and rinse treated areas thoroughly after cleaning. We recommend keeping pets indoors during the service and for about an hour afterward as a standard precaution.

Moss holds moisture against roofing materials, which accelerates deterioration of asphalt shingles, lifts and cracks tiles, and promotes wood rot on cedar shakes. In Portland’s wet climate, unchecked moss growth can shorten a roof’s lifespan by years. The root structures work under shingle edges, allowing water to penetrate the underlayment and cause leaks.

We strongly advise against it. High-pressure water strips the protective granules from asphalt shingles and can crack tiles or splinter wood shakes. Roofs should always be soft washed using low-pressure application with specialized moss and algae treatments. This removes growth effectively while preserving the integrity of your roofing material.

A professional moss treatment typically keeps your roof clear for 12 to 24 months, depending on your property’s sun exposure, tree canopy coverage, and proximity to moisture sources. Properties with heavy shade and overhanging branches may need annual treatments. We offer preventive maintenance plans to keep moss from returning.

Yes, we offer zinc strip installation as part of our moss prevention program. Zinc strips are placed along roof ridgelines and release trace amounts of zinc with each rainfall, creating an environment that inhibits moss and algae growth. Combined with periodic cleaning, zinc strips significantly extend the interval between professional treatments.

For wood decks, absolutely. Cleaning opens the wood pores and removes old finish, making it the ideal time to apply a fresh sealant or stain. Sealing protects against Portland’s heavy rainfall, UV exposure during summer months, and the moisture cycling that causes wood to warp and crack over time. We recommend sealing within a week of cleaning.

We carry transparent, semi-transparent, and solid-color stains from professional-grade product lines. We also offer clear water-repellent sealers for homeowners who want protection without changing the wood’s natural appearance. During your estimate, we can discuss color options and recommend the best product for your wood species and exposure conditions.

Wood surfaces should dry for 24 to 48 hours after cleaning before sealer or stain is applied. The exact timing depends on weather conditions, humidity levels, and wood type. We schedule cleaning and sealing appointments with this drying window built in, and we monitor conditions to ensure proper adhesion and penetration.

Most wood decks in the Portland area benefit from resealing every one to three years, depending on the product used, sun exposure, and foot traffic. Composite and stone surfaces need less frequent maintenance. We can assess your current finish during a free estimate and recommend the right maintenance interval for your specific setup.
