Commercial sealant contractors for Sheerwater sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

For managing agents and facilities managers

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Commercial sealant contractors in Sheerwater

A reseal stands or falls on the preparation underneath it. Silicone has no grip on cured silicone, so the failed bead is cut out completely, then both faces are cleaned back to sound, dry material with no dust or grease on them. Primer is used wherever the manufacturer calls for it on that surface, and a backing rod limits the depth to give the sealant room to work. If you are dealing with earlier reseals applied straight onto the failed bead and leaks that seem to come through a sealant line, we can help, whatever the surface. One point of contact handles commercial sealant work in Sheerwater from the first photographs to the final walk-round, for single jobs and planned programmes alike.

Quotes for commercial sealant in Sheerwater can come from photographs and a joint schedule, or from a walk-round, with the scope listed so everyone knows what’s included.

Work in smaller places such as Sheerwater tends to come one building at a time: a pub kitchen, a hall, a small office. We’ll want a full list and photos first, so the right products come on the day and nothing waits for a second trip.

Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

Common questions from Sheerwater clients

Do hotels near Sheerwater have to close for sealant work?

Almost never. The work is phased so most rooms stay available. The plan is built around your bookings.

Is Sheerwater off your patch?

No. Small places get the same service as large ones. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.

Could the old sealant in an older building contain asbestos?

On older buildings, our first request is the asbestos survey. The duty to manage asbestos sits with the dutyholder and removing it isn’t something we do.

Does weather matter for sealant work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

Can areas stay open during the work?

It’s normal for us to work in occupied buildings. We agree the order of areas, protect what’s nearby and close off only the section we’re sealing.

Is failed sealant stripped out, or sealed over?

Removal of the failed sealant is always part of the job. Laying new silicone on old gives it nothing to grip, and the faces are brought back to sound, dry material before resealing.

What site paperwork can you provide?

Send your site requirements with the enquiry. For older buildings we’ll ask for the asbestos register, plus your site induction rules.

What Sheerwater’s businesses ask us to seal

There are several hotels within about 2 miles of Sheerwater. Refits in hotels bring joints at vanity tops, bar counters and reception desks where the colour has to suit the scheme. There are five care or nursing homes within about 2 miles of Sheerwater. Care settings have kitchens, lounges and corridors where joints need to be neat and easy to clean.

Occupiers with premises at both Kingsway Business Park and Woking Business Park could have the sealant at each handled under one quote. Offices at parks like Kingsway Business Park (to the south-west of Sheerwater) have receptions, kitchens and glazed partitions where a tidy joint matters. Offices and shops close to stations such as West Byfleet station, 1.1 miles to the north-east of Sheerwater, tend to be busy all day, so sealant work is planned around opening hours.

Looking after the joints

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Add sealant to the planned maintenance inspection list
  • Have extract fans checked so wet areas dry out
  • Keep barriers up until the new sealant has cured
  • Check joints after other trades have worked nearby

Keep an eye out for other trades after we have gone. Shop refits, new services and replaced fittings often break the seal around them and the joint gets left open. Where work has disturbed a joint, just phone 01277 525 020 or email a schedule or drawings for a quote.

Each spell of wet weather pushes more water through an open joint. It can run into cavities, insulation and internal finishes long before anyone sees a stain. Catching it at the sealant stage avoids the bigger repair.

Cost factors for sealant joints

Quotes vary with the job. It mainly depends on:

  • Whether the work must be split into stages
  • Which sealant the job calls for
  • Induction, permit and paperwork requirements
  • The total length or number of joints

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Details that help us quote

Good information means a firmer quote. Helpful details to send:

  • Approximate linear metres or a joint schedule
  • Asbestos survey details if the building is older
  • How the joints are reached, and at what height
  • Specification clauses that apply

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.

What sealant work can’t fix

We check first that sealant really is the fix. It won’t put right:

  • Old mastic that tests positive for asbestos
  • Water from a services leak rather than a joint
  • Cracking that needs a structural engineer to look at it

Not sure which it is? You can give us a call on 01277 525 020 or use the quote form and we will tell you honestly.

Surfaces we seal

  • Washrooms and tea points
  • Movement joints in walls and floors
  • Kitchen worktops and splashbacks
  • Floor and threshold joints
  • Window and door perimeters
  • External facade joints

How a job runs

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work typically takes a few hours to several days on most single sites, depending on joint lengths and access. For work around Sheerwater, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. Site photographs, drawings or a visit tell us what’s there and how it has failed.
  2. A fixed quote follows, with removal and preparation included.
  3. We agree the order of work, access windows and site hours with you.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. We hand back each area with its cure time and our 12-month guarantee.

What we need from you

  • Tell us which areas need to stay in use
  • Share the asbestos register for older buildings
  • Explain the parking and delivery arrangements

Why act early in Sheerwater

Sealant is often treated as an afterthought by the trade that fitted the element. A specialist applicator takes care of product choice, joint depth and preparation. It shows over the following seasons rather than at handover. One visit to deal with every failing joint makes more sense than several trips to a place like Sheerwater, rather than one at a time. Send photographs of each area and we’ll quote for the lot.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.
