Stone restoration frequently asked questions

Yes. Many countertops, tables, bathrooms, floors, and repair projects can be evaluated from clear photographs. We normally request one wide photograph showing the entire work area and close-up photographs of the worst damage. Larger, unusual, or commercial projects may require an on-site inspection.

An inspection may be necessary when the stone type is uncertain, the damage is structural, staining may extend below the surface, access is complicated, or the project includes large floors, lippage, exterior stone, multiple rooms, or commercial areas. We will tell you if a site visit is needed after reviewing the initial information.

Pricing depends on the stone type, surface size, condition, desired finish, repairs, access, protection requirements, building rules, parking, materials, and the number of technicians and visits required. Every written proposal identifies the approved scope and price before work begins.

Small repairs may take several hours. Many countertop, vanity, table, or single-room projects are completed in one day, while larger bathrooms, floors, exterior areas, and commercial projects may require multiple days or visits. Your proposal will include the expected duration based on the approved scope.

Most projects require a 50% deposit to reserve the scheduled date, with the remaining balance due upon completion unless the written proposal states otherwise. Scheduling, cancellation, rescheduling, and payment terms are included in the proposal.

Yes. We regularly work in New York City condominiums, cooperatives, managed buildings, hotels, and commercial properties. Send us your building's sample COI or insurance requirements so the certificate can be prepared correctly before the scheduled service.

Stone Guys NY serves Manhattan, Brooklyn, Queens, the Bronx, Staten Island, and surrounding areas of New York, New Jersey, and Connecticut. Availability and minimum project requirements may vary by location.

Often, yes. Professional honing, polishing, cleaning, sealing, and repair can correct many forms of wear without demolition or replacement. We evaluate the material and damage before recommending restoration, repair, partial replacement, or another appropriate solution.

Many surface defects can be removed or substantially improved, but results depend on their depth, cause, location, stone type, prior treatments, and structural condition. Deep stains, pitting, fissures, movement-related cracks, and previous repairs may remain partially visible. We explain known limitations before work begins whenever they can be identified.

We carefully color-match and refinish repairs to blend with the surrounding surface, but natural movement, veining, lighting, repair depth, and the original damage can prevent a perfectly invisible result. The goal is a strong, professional repair with the best practical visual match.

Sometimes, but isolated treatment can leave a visible difference in sheen, texture, or color. Countertops, islands, tables, and continuous floor sections often need to be refinished as a complete surface to produce a uniform result. We will recommend the smallest practical area that can be restored consistently.

Cleaning removes surface soil and compatible buildup. Honing uses abrasives to correct wear, etching, and scratches while producing a matte or satin finish. Polishing refines the stone to a higher sheen when appropriate. Sealing helps the stone resist staining; it does not prevent etching, scratching, cracking, or all moisture-related problems.

Most honing and polishing is performed with controlled wet methods designed to keep airborne dust to a minimum. We protect adjacent surfaces and manage slurry and residue throughout the work. Some repair, preparation, or exterior procedures may create limited dust, and any special conditions will be discussed beforehand.

Technicians protect the immediate work area using appropriate coverings, masking, containment, and controlled equipment. Movable furniture may be relocated when it can be safely handled by two technicians. Fragile, loose, unusually heavy, or unsafe items must be moved by the client or an appropriate specialist before work begins.

Products and methods are selected according to the stone, damage, and work environment. Children and pets should remain outside the active work area until the technicians confirm it is ready for normal use. Tell us in advance about pets, plants, occupied spaces, food-preparation areas, allergies, or other special concerns so appropriate precautions can be discussed.

Yes, most surface etching can be corrected through professional honing and, when appropriate, polishing. Etching is physical damage caused by an acidic reaction; it cannot be cleaned away. If the affected area is part of a continuous surface, the entire section may need refinishing for a consistent appearance.

No. Penetrating sealer helps resist staining by slowing absorption, but it does not stop acidic substances from etching marble, limestone, travertine, or other acid-sensitive stone. Spills should be blotted promptly, and only stone-safe cleaning products should be used.

Many cracks and chips around cutouts can be repaired with professional resin or epoxy systems. We first consider support, movement, moisture, and the condition beneath the stone. If the crack is active or the countertop lacks adequate support, reinforcement or corrective work may be recommended before refinishing.

Certain chips, cracks, seams, scratches, dull areas, and surface defects in engineered quartz can be repaired or improved. Results vary because engineered surfaces contain resin and do not respond like natural stone. Heat damage, UV discoloration, deep burns, and some chemical damage may not be fully reversible.

Yes. We restore marble dining, coffee, and side tables, including many Knoll and Saarinen tulip tables. Services may include coating removal, scratch and etch correction, chip or crack repair, honing, polishing, sealing, and reinforcement recommendations. Photographs of the full table, base, underside, and damage are helpful for evaluation.

Yes. Depending on the condition, shower restoration may include stone-safe cleaning, efflorescence treatment, grout cleaning or replacement, silicone replacement, honing, wall polishing when appropriate, repairs, and sealing. Shower floors are generally finished with a honed or slip-conscious finish rather than a high gloss.

Yes. We can remove and replace deteriorated grout and flexible sealant within the approved scope. Grout, silicone, and stone serve different purposes, so the correct material must be used at joints, corners, perimeters, backsplashes, thresholds, and other transitions.

Many deposits and surface discolorations can be treated, but the cause must be considered. Recurring moisture, leaks, failed waterproofing, drainage problems, or contamination behind the stone may require a plumber, waterproofing contractor, or other specialist. Restoration improves the accessible surface but does not repair concealed building conditions unless specifically included.

Return-to-use time depends on the sealer, grout, silicone, adhesive, repair material, temperature, humidity, and scope. Your technicians will provide project-specific instructions. Do not expose the surface to water, cleaning products, food, or heavy use until the stated curing time has passed.

There is no universal schedule. Maintenance depends on the stone, finish, traffic, exposure, cleaning practices, previous treatments, and current condition. High-use countertops, showers, and commercial floors may need attention sooner than decorative walls or lightly used areas. We recommend service based on inspection and performance rather than an automatic calendar interval.

Darkening from absorbed water, increasing stain sensitivity, or a failed absorption test may indicate that resealing should be considered. Not every stone or engineered surface requires sealer. The correct product and timing depend on the material, location, existing treatment, and sealer manufacturer's instructions.

Use a pH-neutral cleaner specifically labeled for natural stone and follow the manufacturer's dilution instructions. Avoid vinegar, lemon, acidic bathroom cleaners, abrasive powders, harsh alkaline degreasers, acetone, bleach mixtures, and general-purpose glass cleaners unless a product has been confirmed as compatible with your exact surface and treatment.

Yes. We explain the curing period, normal-use restrictions, recommended cleaning practices, and relevant maintenance considerations for the completed work. Contact us before using an unfamiliar chemical or attempting a DIY repair on a restored surface.

Yes. We work with homeowners, property managers, boards, hotels, restaurants, retailers, general contractors, architects, and designers. Commercial scopes can include lobbies, corridors, elevators, stairs, bathrooms, countertops, exterior stone, periodic polishing, repairs, sealing, and planned maintenance.

When project conditions and building rules allow, commercial restoration can be planned in phases or scheduled to reduce disruption. Access, noise restrictions, elevator use, loading requirements, cure times, and operating hours should be discussed during estimating.

Yes. Maintenance plans are customized after evaluating the stone, traffic, current condition, finish, and operational needs. The written plan identifies the covered areas, services, frequency, exclusions, scheduling, and pricing; it is not an unlimited subscription to every repair or restoration service.
