Service Deep-Dive

House Soft-Wash

Safe-Pressure Exterior Restoration

Starting at $299

Standard high-pressure washing is a risk to your home’s integrity. Knight Exterior Care utilizes a specialized Soft-Wash system designed for high-end residential properties. Our low-pressure, chemistry-first approach uses professional-grade, eco-friendly detergents to kill mold, mildew, and algae at the root. This ensures a deeper clean that lasts up to 3x longer than traditional power washing, all while protecting your siding, paint, and landscaping.

How Our Pricing Works:

To provide transparent pricing that accounts for the actual difficulty of the clean, we use a straightforward multiplier based on your home’s total interior living area (square footage) and the number of stories. All projects are subject to a $299 minimum base rate.

  • Single-Story Homes: $0.25 per sq. ft.

  • Two-Story Homes: $0.30 per sq. ft.

  • Three-Story / Walk-Out Basement Homes: $0.35 per sq. ft.

Self-Quote Example: If you have a 2,500 sq. ft. two-story home, your calculation is simply 2,500 x $0.30 = $750.00.

Disclaimer: Rates are based on the removal of standard organic growth (mold/algae) on standard exterior substrates (vinyl, brick, and fiber-cement/Hardie board). Specialized materials and conditions—including delicate natural wood (Cedar) siding, heavy oxidation (chalky residue), artillery fungus, or rust stains—require dedicated restoration chemistry and are quoted separately following a physical or photo inspection.

Roof Restoration Soft-Wash

No-Pressure Shingle Preservation

Starting at $349

Those black streaks on your shingles aren’t just dirt—they are a hardy form of algae that feeds on your roof’s limestone, causing premature shingle failure and increasing energy costs. Knight Exterior Care utilizes an industry-standard No-Pressure Soft-Wash treatment. This process kills algae, moss, and lichen at the root, restoring your roof's appearance and heat-reflecting properties without the risk of granule loss or shingle damage.

How Our Pricing Works:

Roof restorations require heavy-duty safety protocols, specialized chemistry, and meticulous landscaping protection. To provide accurate pricing, we use a multiplier based on your home's total footprint (including the garage) and the difficulty of the roof's height and pitch. All projects are subject to a $349 minimum base rate.

  • Standard / Walkable Roofs (Single-Story, Low Pitch): $0.30 per sq. ft.

  • Steep / Non-Walkable OR 2-Story Roofs: $0.40 per sq. ft.

Self-Quote Example:

If your home and garage have a combined footprint of 2,000 sq. ft. and your roof is steep or on a two-story home, your calculation is 2,000 x $0.40 = $800.00.

Disclaimer: Rates are based on the removal of standard organic growth (black algae streaks) on asphalt shingle roofs. While our treatment kills heavy moss and lichen instantly, these growths have root-like structures anchored into the shingles; they will remain visible until natural weathering (rain and wind) safely detaches them over the following weeks. Please note that 3+ story homes, extremely complex rooflines, or non-asphalt shingles (slate, tile, or cedar) require a custom quote due to increased safety requirements and specialized equipment.

Driveway & Concrete Surface Cleaning

Commercial-Grade Hot Water Restoration

Starting at $149

Standard cold-water cleaning only hits the surface. Knight Exterior Care uses 200°F industrial heat to melt through traffic film, grime, and organic growth. We kill mold and algae at the root for a deeper clean that lasts significantly longer than traditional pressure washing.

How Our Pricing Works:

To provide transparent pricing that accounts for the fuel and specialized equipment required for hot-water extraction, we use a straightforward, two-tier pricing model based on your surface’s total area (square footage):

  • The Foundation: Every project starts with a $149 base rate (covering your first 500 sq. ft.).

  • The Extra Space: Any additional area beyond 500 sq. ft. is billed at a flat $0.28/sq. ft.

Self-Quote Example:

If you have a 1,500 sq. ft. driveway, your calculation is simply: 1,000 extra sq. ft. x $0.28 = $280. Add the $149 base rate, and your total is $429.00.

Disclaimer: Rates are based on standard organic growth (mold/algae) and typical surface dirt. Due to the specialized chemicals, hot water extraction, and extended labor required, surfaces with heavy automotive oil saturation, thick grease, or severe rust staining will be quoted separately after a physical or photo inspection.

Gutter Cleaning

Debris Removal & Downspout Flushing

Starting at $129

Clogged gutters do more than just overflow—they lead to foundation erosion, basement flooding, and costly wood rot along your roofline. Knight Exterior Care provides a comprehensive debris removal service that goes beyond the basics. We hand-clear all organic matter and perform a high-volume downspout flush to ensure your entire drainage system is operating at 100% capacity before the next NWA storm hits.

How Our Pricing Works:

To provide transparent pricing that accounts for the constant ladder transitions required for safe clearing, we use a straightforward, two-tier pricing model based on the total length of your gutter system (linear footage):

  • The Foundation: $129 base rate (covers your first 100 linear feet).

  • The Extra Length: $1.25 per linear foot for any additional length.

Self-Quote Example: If you have a home with 250 linear feet of gutters, the foundation base rate covers the first 100 feet ($129). The remaining 150 feet are billed at $1.25/ft ($187.50). Your total would be $316.50.

Disclaimer: Rates are based on standard debris removal (leaves, pine needles, and silt) on one story homes. Please note that 2+ story homes or those requiring specialized ladder maneuvers will be quoted separately to account for increased safety requirements. Gutter guards or screens that require removal and re-installation for cleaning will be quoted as a separate labor charge. While we ensure downspouts are clear to ground level, clogs within underground French drains or PVC drainage pipes are outside our standard scope and require specialized plumbing or excavation services.

Fence Cleaning

Professional Care for Wood & Vinyl Perimeters

Starting at $149

A clean fence is more than just curb appeal—it’s the frame that defines your property. Because wood and vinyl require completely different cleaning methods, Knight Exterior Care uses material-specific chemistry to ensure a safe, deep clean:

  • For Wood Fencing: We use a specialized Low-Pressure Conditioning process. Instead of blasting the wood with high pressure, we apply a professional-grade cleaner to lift gray oxidation and mold, followed by a neutralizing acid rinse. This restores the wood's natural pH balance and original color without damaging the delicate fibers.

  • For Vinyl Fencing: White vinyl is prone to green algae and black "tiger stripes." We utilize a Soft-Wash Algae Treatment that chemically melts away organic growth and pollution film. This restores the bright, "factory-new" finish without the need for abrasive scrubbing or high-pressure water that can crack or etch the surface.

How Our Pricing Works:

Fences are measured by linear footage. Because we must treat the interior and exterior of the fence separately, rates are calculated per linear foot, per side.

Standard Vinyl / PVC Fencing:

  • The Foundation: $149 base rate (covers your first 100 linear feet of surface).

  • The Extra Length: $1.50 per linear foot, per side.

Natural Wood Restoration (Two-Step Process):

  • The Foundation: $149 base rate (covers your first 75 linear feet of surface).

  • The Extra Length: $2.00 per linear foot, per side.

Self-Quote Example: If you have 150 linear feet of vinyl fencing along your backyard and want both the inside and outside washed, you have 300 total feet of surface. The foundation base rate covers the first 100 feet ($149). The remaining 200 feet are billed at $1.50/ft ($300). Your total would be $449.00.

Disclaimer: Rates are based on standard organic growth (mold/algae) and light oxidation. This service is a deep-cleaning and conditioning treatment; it does not include sanding, staining, or structural repairs. Vinyl fencing with heavy "hard water" staining or wood fencing with severe structural rot will require a custom quote following a physical inspection.

Deck Cleaning

Safe Care for Wood & Composite Surfaces

Starting at $149

Your deck is an extension of your home’s living space, but whether it's natural wood or modern composite, it requires specialized care. Knight Exterior Care utilizes a Low-Pressure Soft-Wash system that treats your deck with the specific chemistry it needs:

  • For Natural Wood: We use professional-grade conditioners to lift "silver-gray" oxidation and mold. Our two-step process restores the wood's natural pH balance, preventing splintering and "furring" caused by traditional pressure washing.

  • For Composite: While durable, composite decks are prone to deep-seated mold and black spots. We use manufacturer-approved detergents that safely kill organic growth and lift stains without the high pressure that can etch the surface or void your warranty.

How Our Pricing Works:

Because natural wood requires a specialized two-step chemical restoration, we use a two-tier pricing model based on your deck’s material and total surface area (square footage):

Standard Composite / PVC Decks:

  • The Foundation: $149 base rate (covers your first 300 sq. ft.).

  • The Extra Space: $0.50 per sq. ft. for any additional area.

Natural Wood Restoration (Two-Step Process):

  • The Foundation: $149 base rate (covers your first 200 sq. ft.).

  • The Extra Space: $0.75 per sq. ft. for any additional area.

Self-Quote Example: If you have a 500 sq. ft. natural wood deck, the foundation base rate covers the first 200 sq. ft. ($149). The remaining 300 sq. ft. are billed at $0.75/sq. ft. ($225). Your total would be $374.00.

Disclaimer: Rates cover the removal of standard organic growth (mold/algae) and light oxidation. Wood Restoration involves a cleaning and brightening treatment; it does not include sanding, staining, or structural repairs. Stripping old solid-color stains or peeling paint is an intensive restoration process and will be quoted separately following a physical inspection.

Stone and Paver Hardscape Cleaning

Safe, Deep-Cleaning for Patios, Walkways, & Porches

Starting at $149

Stone and paver surfaces are the highlights of your landscaping, but porous materials and deep joints are magnets for moisture, moss, and black algae. Knight Exterior Care uses a specialized low-pressure treatment designed to preserve vital joint sand while deep-cleaning delicate stone. Unlike traditional high-pressure washing that can blast out your patio's foundation, our chemistry-first approach melts away the "slick" organic film while protecting the integrity of your outdoor paths.

How Our Pricing Works:

To provide transparent pricing that accounts for the meticulous care required around delicate joint sand, we use a straightforward, two-tier pricing model based on your Hardscape’s total area (square footage):

  • The Foundation: $149 base rate (covers your first 300 sq. ft.).

  • The Extra Space: $0.50 per sq. ft. for any additional area.

Self-Quote Example: If you have a 600 sq. ft. paver patio and walkway system, the foundation base rate covers the first 300 sq. ft. ($149). The remaining 300 sq. ft. are billed at $0.50/sq. ft. ($150). Your total would be $299.00.

Disclaimer: Rates are based on the removal of standard organic growth (mold/algae) and light lichen. While our low-pressure method is specifically chosen to protect joint integrity, natural displacement of loose or failing sand may occur during the cleaning process. Heavy weed removal or full re-sanding are considered restoration services and will be quoted separately.

Specialty & Custom Cleaning

Bespoke Pressure & Soft-Wash Solutions

Starting at $149

Not every exterior cleaning project fits into a neat category. Whether you need your brick entrance columns restored, premium vinyl outdoor furniture refreshed, stubborn rust stains erased from your stonework, or a residential trash bin sanitized, Knight Exterior Care delivers specialized solutions. We analyze the specific substrate, select the correct chemical restoration agents, and carefully adjust our pressure to safely clean your unique property items without risk of damage.

How Our Pricing Works:

Because custom jobs vary widely in materials and complexity, we price our specialty services using a straightforward baseline framework:

  • The Foundation: Every custom project carries a $149 minimum service fee to cover professional dispatch, equipment setup, and chemical logistics.

  • The Custom Estimate: Projects are bid upfront based on structural square footage, required chemical intensity, or total labor hours. Send us a photo or an address for a rapid, guaranteed quote.

Disclaimer: Base rates cover the removal of standard organic growth (mold, mildew, and algae). Specialty environmental stains—including deep automotive oil saturation, battery acid burns, fertilizer rust streaks, or calcium efflorescence—require intensive restoration chemistry and extended dwell times, which will be itemized separately. Delicate or aged items may require a pre-inspection waiver to ensure washing can proceed safely.
