Commercial sealant contractors in Bray Wick, done properly

Getting a price for commercial sealant contractors in Bray Wick doesn’t need to be drawn out. 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. Site teams most often ask us about frame sealant that has cracked, shrunk or pulled away and weathered facade sealant that no longer flexes, on washrooms and tea points, kitchen worktops and splashbacks and external facade joints. Searching for sealant specialists in Bray Wick? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

A lot of what we do in Bray Wick is replacing sealant that has done its years: hardened, cracked or shrunk away from the faces, and letting water or dirt in.

Business units in the countryside around places like Bray Wick are often converted barns, stables or farmyards. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently, and a sealant colour that suits the building’s character is often part of the brief.

We stand by our work with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

When to call us in Bray Wick

The wrong sealant in the wrong place is a common cause of early failure. Painters’ acrylic in a moving joint, vinegar-smelling silicone on metal or natural stone, or a high-modulus product where a low-modulus one was needed all let go sooner than they should. BS 6213 gives guidance on choosing construction sealants, and many specifications refer to it.

Look out for the following:

  • Expansion joints with the sealant torn out
  • Black mould through washroom sealant that won’t clean off
  • Hardened, chalky sealant on south-facing or exposed elevations
  • Smeared sealant across finishes from a rushed job

A business with units at Priors Way Industrial Estate and Trade Park needn’t use two contractors for its sealant.

What to look for in a quote

  • Whether their applicators hold CSCS cards
  • Their public liability cover
  • What the guarantee covers, and for how long
  • What site paperwork they can supply

Choosing a commercial sealant contractor

Our process

At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. Smaller jobs around Bray Wick can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.

  1. You send photographs, drawings or a list of the joints and areas involved, and a site visit is booked where it helps.
  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. Failed sealant is cut out and each joint cleaned back to sound, dry faces.
  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

  • Let building users know which areas are affected
  • Tell us which areas need to stay in use
  • For older buildings, check the asbestos register before work

Related advice

General trades versus a specialist

Putting right a botched joint often costs more than sealing it well at the start, 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.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

Questions about Bray Wick

Do hotels near Bray Wick have to close for sealant work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. We agree the order of rooms and the timings with you before we start.

Is a smaller place like Bray Wick outside your area?

Not at all. Bray Wick is within our area. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

What do you need from us to quote?

Send photos, drawings or a list of locations through the quote form on this site. If a visit is needed we will book one, and a fixed quote follows.

What about asbestos in old mastic?

In buildings from before 2000 in particular, some old mastics and sealants may contain asbestos. Before cutting anything out, we ask for the asbestos register or survey, and anything suspect is left until it has been tested.

How long does a typical visit take?

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

How do you choose the sealant?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Is it OK to apply fresh sealant over existing beads?

Removal comes first, every time. After that come cleaning, primer where needed, backing and the new sealant.

Cost factors for sealant joints

To price the job, we consider:

  • Whether old sealant has to be cut out first
  • The total length or number of joints
  • Any access equipment needed
  • Distance, for remote addresses

What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.

What we need to price the job

However big the job, these details speed things up:

  • The site address and postcode
  • Anything awkward about access or site hours
  • Photos of the joints, close up and from further back
  • Your programme or deadline

The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or give us a call on 01277 525 020 or send photos by email to discuss it first.

What the job involves on each surface

Facade and cladding joints

Panel joints on cladding and rendered facades open and close with the temperature. 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.

Fire-rated seals where specified

Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the product’s tested detail. Fire-stopping design and sign-off sit with the designer, fire engineer or building control, and we install to the specification.

After the work

To get the most from the new sealant:

  • Add sealant to the planned maintenance inspection list
  • Ask cleaners to use a soft cloth and mild cleaner on sealant
  • Check the asbestos register before anyone disturbs old sealant in an older building
  • Ask fit-out and M&E contractors to report any sealant they disturb

Add the resealed joints to your planned maintenance inspections. Regular checks pick up small failures before they become leaks. Should something look amiss, you can ring 01277 525 020 or email drawings and photos and send a picture.

In kitchens and washrooms, a failed joint is a cleaning problem as well as a leak risk. Environmental health officers look at how cleanable surfaces are, which makes sound joints worth keeping on top of.
