Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

What sets the cost

Before we quote, we look at:

  • The site’s rules and procedures
  • Any access equipment needed
  • Quantities, in metres or numbers
  • Backing rod, priming and other preparation

A quote for sealant joints depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.

Details that help us quote

Whether it’s one area or a whole building, the same details help:

  • How the joints are reached, and at what height
  • Any dates the work must fit around
  • Whether the building will be occupied during the work
  • Asbestos survey details if the building is older

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, give us a call on 01277 525 020 or use the quote form.

Sealant specialists in Westwell Leacon

Pricing a commercial reseal is a short process. Send photos, drawings or a schedule of the joints through our quote form. If the joints need seeing in person, a site visit comes first, followed by a fixed quote rather than an estimate that drifts. The enquiries we see most involve a top-up bead over failed sealant, now lifting and hardened, chalky sealant on south-facing or exposed elevations, across floor and threshold joints, external facade joints and kitchen worktops and splashbacks. A single leaking joint is often how a building in Westwell Leacon first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Quotes for commercial sealant in Westwell Leacon can come from photographs and a joint schedule, or from a walk-round, and the scope is set out in writing.

In and around smaller places such as Westwell Leacon, the commercial buildings we’re asked about are often pubs, shops, village halls and barns converted to offices. Kitchens, toilets and window frames in all of them need resealing sooner or later.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Sealant on show in Westwell Leacon’s commercial buildings

That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings.

Questions we’re asked in Westwell Leacon

Is Westwell Leacon too far out for you?

Not at all. Westwell Leacon is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

What site paperwork comes with a job in Westwell Leacon?

RAMS, insurance certificate, CSCS details: list what the site needs and we’ll confirm it with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.

How long do sealant joints last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Can one contractor look after sealant on all our buildings?

Yes. We take on runs of jobs across portfolios as well as single sites, priced site by site or as one programme.

How long does a typical visit take?

The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.

Are you CHAS accredited?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Will the building have to shut 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 are sealing, until its cure time has passed.

Diagnose, treat, sign off

At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. If others near Westwell Leacon need work, visits can be combined. You will have a fixed quote before work starts.

  1. We begin with whatever information you have, whether that’s photos, a drawing or a list of locations.
  2. We work out why the joints have failed and fix a quote for the agreed scope.
  3. Site hours, access windows and the order of areas are agreed before we start.
  4. We strip the failed bead and prepare both faces of the joint.
  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.

Getting the site ready

  • Flag any permit to work we will need
  • Send asbestos survey details if the building is pre-2000

Common problems we fix in Westwell Leacon

A good share of the joints we inspect were topped up instead of being renewed. Fresh sealant won’t stick to the old bead underneath, so the top layer lifts, holds water and hides what’s going on. By the time it shows, there can be two or three layers to cut out.

Typical triggers for a call:

  • Damp patches where an external joint has failed
  • Messy, uneven beads from earlier work that let the building down
  • Greasy, split joints in a kitchen or tea point
  • Layers of sealant, all of them failing

A lasting commercial joint around Westwell Leacon begins with the old bead fully out and the faces clean and dry.

Questions to ask before you book

  • The terms of the workmanship guarantee
  • How the joint faces will be prepared and primed
  • How joint depth will be controlled
  • Will failed sealant be removed rather than covered?

How to choose a sealant contractor

Aftercare for building managers

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Look at the sealant around anything that has been moved or replaced
  • Make sure ventilation in wet areas is switched on and working
  • Ask cleaners to use a soft cloth and mild cleaner on sealant
  • Check sealant as part of routine building inspections

Keep an eye out for other trades after we have gone. When fittings are moved or cabling added, the sealant nearby is easily disturbed and the joint gets left open. Where work has disturbed a joint, just give us a call on 01277 525 020 or send photos by email for a quote.

Occupiers often notice failing sealant before the facilities team does, and in a hotel, office or shop it makes the whole space look neglected. Replacing it on a planned cycle keeps complaints down.

Different surfaces, different methods

Fire-rated seals where specified

Intumescent and other fire-rated sealants go in at service penetrations and linear gaps to the maker’s tested details, where they are specified. Fire-stopping design and sign-off sit with the designer, fire engineer or building control, and we install to the specification.

Window and door perimeters

Where frames meet the surrounding wall, sealant is the weather line. We remove the old seal, prepare the faces, fit backing where needed and seal again with a product chosen for both the frame and the wall.

What we can’t put right

Honesty saves time and money. New sealant won’t cure:

  • Leaking roofs, gutters or flat-roof membranes (those need a roofer)
  • Faulty windows rather than failed perimeter sealant
  • Leaks from pipework, wastes or valves (that’s plumbing)

If in doubt, call the office on 01277 525 020 or send photos by email and we’ll say what we think before you book.
