Commercial sealant contractors for Westcott sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Common problems we fix in Westcott

External sealant takes a steady beating from the weather. UV hardens the surface while wind and rain work at the edges. Once it stiffens, the joint opens up at the next big temperature swing.

Any of the following is a good reason to get the joints checked over:

  • Gaps behind commercial kitchen worktops and sinks
  • Expansion joints with the sealant torn out
  • Untidy joints in a reception, shop floor or lobby
  • Earlier reseals applied straight onto the failed bead

Premises within reach of Dorking West station, 1.4 miles to the north-east of Westcott, often have busy frontages where joints are seen by everyone passing.

What your quote should include

  • How long is the guarantee, and what does it include?
  • Can the work be phased to keep areas open?
  • How joint depth will be controlled
  • Whether old or failed sealant will be cut out, not overlaid

Our contractor checklist

Sealant specialists in Westcott

If you look after more than one building, a single sealant contractor saves a lot of chasing. We take on one-off reseals, runs of jobs across a portfolio and planned maintenance programmes, run the same way on every site: send details, get a fixed quote, we seal, and a 12-month guarantee once it’s signed off. To get a programme moving in Westcott, speak to us on 01277 525 020 or email a schedule or drawings with the site addresses. We work on window and door perimeters, washrooms and tea points and kitchen worktops and splashbacks, and what we are called in for most is frame mastic that has hardened and come away from the wall and damp patches where an external joint has failed. A specialist sealant contractor works differently from a general builder: in Westcott, that means joint design, primers and backing rod as standard.

We price commercial jobs in Westcott from photos, drawings or a site visit, with the scope listed so everyone knows what’s included.

A job in a smaller place like Westcott is typically a single building. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

On site: what to expect

Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Rural sites near Westcott may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. You send photos, drawings or a list of the joints and areas involved, and a site visit is booked where it helps.
  2. Next comes a diagnosis and a fixed quote.
  3. Before anything is cut out, we agree access, timings and sequence.
  4. The failed bead is removed and the joint faces cleaned until they’re sound and dry.
  5. We fit backing to the right depth, prime where specified and lay the new bead.
  6. Each area is inspected, signed off and backed by our 12-month guarantee.

Before we start on site

  • Send your site hours and access windows
  • Tell us which areas need to stay in use
  • Share the asbestos register for older buildings

Maintenance after handover

Problems stay small when the joints are checked regularly. Specifically:

  • Add sealant to the planned maintenance inspection list
  • Check joints after other trades have worked nearby
  • Have extract fans checked so wet areas dry out
  • Keep abrasive pads and scrapers off resealed joints

Put sealant on the planned maintenance checklist. A periodic look catches splits and lifting edges early, with external elevations and wet areas first in line. Should something look amiss, you can call the office on 01277 525 020 or use the quote form and send a picture.

Once sealant fails in a movement joint, grit and debris get in. With nothing soft to close against, the materials either side take the load and start to break up. At that point it’s a repair job rather than a reseal.

How the job changes by surface

Washrooms and toilets

Mould that has grown into washroom sealant can’t typically be cleaned out. The lasting answer is removal, preparation and a new sanitary bead, planned so the building keeps enough facilities in use.

Facade and cladding joints

Facade joints move every day as panels warm and cool. The product has to suit the movement, and the depth has to be controlled with backing. Access, such as scaffold already up, is agreed before the price is fixed.

General trades versus a specialist

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

For managing agents and facilities managers

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Westcott can form part of a wider programme.

Questions about Westcott

Is Westcott off your patch?

No. Places such as Westcott are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Do hotels near Westcott have to close for sealant work?

Almost never. The work is phased so most rooms stay available. We agree the order of rooms and the timings with you before we start.

Do you work for facilities managers and managing agents?

Yes. Use our quote form to send the site details, or phone or email us, and tell us what site paperwork you need.

Do you take on multi-site sealant work?

Yes. We regularly take on multi-site work and planned maintenance programmes.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards.

Do you hold CHAS accreditation?

Yes. We’re CHAS accredited and a Constructionline member.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

Sealant on show in Westcott’s commercial buildings

Westcott has four care or nursing homes no more than 2 miles away. Care homes need tidy, cleanable joints in kitchens, corridors and communal rooms. Rainfall across the South East, Westcott included, is lower than in many parts of the UK. Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it.

A unit on an estate like Chapel Lane Industrial Estate (to the north of Westcott) typically has an office front, a trade counter and staff facilities with joints of their own. If you have premises on more than one site, say at Chapel Lane Industrial Estate and Glebelands Centre Business Park, one contractor and one quote can cover both.
