Frequently Asked Questions

Pressure washing uses high-pressure water, great for concrete driveways. Soft washing uses low pressure plus biodegradable cleaning agents, required for roofs, siding and screens. Using high pressure on the wrong surface causes damage. We use the right method for every surface.

Tampa Bay's humidity encourages mold and mildew growth fast. We recommend a house wash at least once per year. Coastal homes and homes surrounded by trees often need twice-yearly service.

Yes. when done correctly. We pre-soak landscaping with water, use only biodegradable, plant-safe detergents, and rinse thoroughly. Plant damage is virtually unheard of when pressure washing is handled by trained professionals.

A standard 2,000 sqft home takes 2–4 hours for a house wash. Driveway adds 30–60 minutes. Full-property cleans (house + roof + driveway + gutters) typically 4–6 hours.

Not with soft washing, which is what we use on siding. High-pressure on vinyl or painted surfaces can cause damage. Our soft-wash low-pressure system plus biodegradable detergents is safe for every siding type.

We prefer you be home for the initial walkthrough, but we can complete most jobs in your absence. We text photo updates throughout and send a full photo report on completion.

Yes. $2M general liability plus workers' comp on every crew member. Every job is fully covered from arrival to departure.

Yes. in writing. Paver sealing carries a 3-year warranty, shingle roof soft washing a 2-year spot-clean warranty, and every service our 100% satisfaction guarantee. Full terms: krystalkleanexterior.com/warranty.html

Timing depends on square footage, cleaning needs, whether failed sealer must be stripped, drying conditions and the coating system. We explain the schedule and weather plan with the estimate.

From our Paver Sealing page.

Many Florida projects are inspected for a topcoat refresh around 18 to 24 months, but exposure, drainage, traffic and product choice all affect timing. Qualifying systems include a written 2- or 3-year failed-sealer warranty.

From our Paver Sealing page.

A color-enhanced system gives the pavers a richer semi-wet or wet look. A natural penetrating system protects with less visible sheen. We match the product to the paver material, porosity and finish you want.

From our Paver Sealing page.

We replace loose, low or contaminated joint material as the project requires. Standard projects typically use ASTM C144 joint sand. Polymeric sand is a separate option for unusually wide joints or sand-only scopes where it is the better fit.

From our Paver Sealing page.

Yes, but we use a penetrating impregnating sealer on natural stone, never a film-forming topical sealer. Wrong product on stone traps moisture and causes spalling. We only use stone-appropriate, pH-neutral products.

From our Paver Sealing page.

We pressure wash and spot-treat stains before sealing. Most stains come fully clean. Deep oil stains may need extra pre-treatment, we'll flag any concern before sealing.

From our Paver Sealing page.

We'd prefer you be home for at least the walkthrough at the start and end, but we can complete the work in your absence. We'll photo-document everything and text you updates.

Most Tampa Bay paver sealing projects run $349 to $1,895. A standard two-car driveway usually lands in the $349 to $795 range, while larger pool decks, screened lanais and wraparound patios run higher. The biggest price drivers are square footage, joint condition, drainage, porosity, stripping needs, product choice and the number of coats.

From our Paver Sealing page.

Five things move the number: total square footage across driveway, walkway, patio and pool deck; the condition of the joint sand (heavy washout means more re-sanding); whether a previous failed or peeling sealer needs stripping before we can reseal; the paver material (travertine and natural stone require a pricier penetrating sealer, never a topical film); and your finish (wet-look high-gloss vs. natural matte). We break every line item out on the estimate so there are no surprises.

From our Paver Sealing page.

Our crews have completed more than 3,700 paver projects in the past five years. Krystal Klean is led by a Trident Master Certified technician who trains other contractors, and qualifying systems include a written 2- or 3-year failed-sealer warranty.

From our Paver Sealing page.

In Florida's UV, humidity, afternoon rain and salt exposure, unprotected pavers can fade, stain and lose joint material. A correctly selected sand and sealer system helps stabilize the joints, slow color loss and make maintenance easier. The inspection tells us whether sealing, a maintenance coat or full restoration is the right next step.

From our Paver Sealing page.

Usually yes. White or milky sealer is often moisture trapped under a topical coating, over-application, or incompatible sealer. We inspect first, then recommend a partial strip, full strip, or restoration clean depending on the failure.

From our Paver Stripping & Restoration page.

Not every cloudy surface needs stripping, but a connected paver field with failed sealer usually cannot be patch-stripped without risking uneven porosity, color and sheen. We test the coating first and recommend maintenance, cleaning, a separate-area correction or a full strip based on what will finish evenly.

From our Paver Stripping & Restoration page.

Most restoration projects take multiple visits because stripping, cleaning, drying, sanding, and sealing cannot be rushed in Florida humidity. Small driveways may take 2-3 visits; larger pool decks or failed coatings can take longer.

From our Paver Stripping & Restoration page.

Yes, but travertine and natural stone need a different approach than concrete pavers. We use stone-appropriate cleaning and penetrating sealers, never a film-forming topical coating that traps moisture.

From our Paver Stripping & Restoration page.

If the joints are low, loose, contaminated, full of weeds or washing out, they should be corrected before sealing. We select the joint material based on width, depth and scope instead of automatically using polymeric sand.

From our Paver Cleaning & Re-Sanding page.

Polymeric sand contains binding additives and is activated with water. We consider it for unusually wide joints, often more than about one-half inch, or for sand-only scopes where the selected product is compatible with the pavers and joint width.

From our Paver Cleaning & Re-Sanding page.

We typically use ASTM C144 joint sand in the color selected for the project. When sealing is included, the flood-coat system stabilizes that sand inside the joints.

From our Paver Cleaning & Re-Sanding page.

Yes. Some customers only need cleaning and re-sanding. We will recommend sealing when it makes sense, but we do not force it if the surface does not need it yet.

From our Paver Cleaning & Re-Sanding page.

Pressure washing uses high-pressure water, great for concrete, but it can damage siding, paint and screens. Soft washing uses low pressure plus biodegradable detergents, far safer for your home and more effective at killing algae and mildew at the root.

From our House Washing page.

At least once a year. Coastal homes, north-facing homes and homes surrounded by trees often need it twice a year because of salt air, humidity and shade encouraging algae.

From our House Washing page.

No. We pre-soak landscaping with water, use biodegradable detergents, and rinse everything thoroughly. We tarp delicate plants when needed and photo-document landscaping before and after, protecting your plants is part of the process, not an afterthought.

From our House Washing page.

Most Tampa Bay house washing jobs run $249 to $795. A typical single-story 1,500 to 2,000 sqft home usually falls in the $249 to $449 range; two-story homes, larger footprints and heavily soiled or coastal properties run higher. Price depends on square footage, number of stories, siding type and how much algae and mildew has built up. We give free on-site or photo estimates before any work starts.

From our House Washing page.

Square footage and the number of stories are the biggest factors, followed by siding type (stucco and textured surfaces hold more mildew than smooth vinyl), how much organic growth has accumulated, and access challenges like tight side yards, screen enclosures or delicate landscaping. Coastal homes near the Gulf often need a stronger detergent mix because salt air accelerates buildup, but our biodegradable soft-wash system stays gentle on the siding either way.

From our House Washing page.

Yes. Green algae, black mildew streaks and gray grime are living organic growth, and our soft-wash detergents kill them at the root rather than just blasting the surface. That's why results last 12 to 18 months in Tampa Bay instead of returning within weeks like a plain pressure rinse.
