Facade sealing near Slough

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

How the job changes by surface

Window and door perimeters

Aluminium, PVC-U and timber frames each have their own preparation needs. Primer goes on where the manufacturer specifies it for that substrate.

Render and coated surfaces

Paintable sealants exist for joints that will be coated. The choice depends on the specification and finish.

Facade sealing in Slough, done properly

Every facade quote starts with how the joints will be reached. Let us know what access exists or is planned, and any site rules we need to work around, so the price covers the real job. We work on perimeter joints where frames meet the structure, cladding panel joints and coping and flashing joints, and the failures we’re asked to look at most are patch repairs that keep failing and staining on stone next to old sealant. For commercial sealant work in Slough, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

On larger schemes in and around Slough, mastic is often programmed plot by plot or floor by floor. Our CSCS-carded applicators follow the site induction and specification, and snags are closed before handover.

Every job we finish is backed by a 12-month workmanship guarantee, in Slough as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

General trades versus a specialist

Redoing a failed joint typically 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 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.

Common questions from Slough clients

Is hospital work, at somewhere like Upton Hospital, something you do?

Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.

Will you take on work at estates like Slough Business Park, close to Slough?

Yes. Our area takes in Slough and its surroundings, with estates and business parks such as Slough Business Park included. Photos and a short description are enough for a first look.

Do you install glazing systems?

No. Glazing, windows and glass replacement aren’t part of our work. We seal the joints around them, including perimeters where frames meet the structure.

How long will the new sealant last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

Do you provide access for facade work?

That varies with the building and the access on offer. When you call the office on 01277 525 020 or email a schedule or drawings, describe the access, and we will agree the approach together.

Do you offer coloured sealant?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.

Facade sealing in Slough: the local picture

Slough is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, which is why external dates are agreed with the site manager. Slough lies roughly 22 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme.

For contractors at a college like Windsor College, 2.5 miles to the south of Slough, perimeters and internal sealant are timed for the holidays. On a healthcare site such as Upton Hospital, 0.9 miles south-east of Slough, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Hotel extensions and refits, at places such as Copthorne Hotel Slough - Windsor, which lies south-west of Slough, usually run between busy periods, so the sealing is squeezed into short windows.

Slough is about 22 miles west of London, in Slough. We cover Slough, with the same fixed quotes and 12-month guarantee as everywhere else. Our Slough coverage takes in 11 places. For work in that direction, see our Reading page (17 miles or so).

Commercial sites across SL1, SL3, SL2 and SL6 are covered. If your site is on High Street, Station Road and London Road or close by, we can quote for facade joints. Main routes into Slough include the A4 and A332. Nearby places we also cover include Chalvey (1 mile south), Cippenham (1 mile west), Britwell (1 mile north-west), Farnham Royal (2 miles north) and Huntercombe (2 miles west).

Landmarks near Slough

Around Slough, our work takes us to commercial buildings near Westgate School, Herschel Park and The Moon and Spoon pub and the streets around them.

Not far away are Taplow Lake and Burnham Beeches.

Diagnose, treat, sign off

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself normally taking longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. Bigger buildings in Slough are normally done in phases agreed with the site or facilities manager, so the building keeps working. Photos and drawings let us propose a sequence with the quote.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out in full.
  4. Primer is applied where the maker specifies it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

Preparing the site

  • Confirm the product named in the specification
  • Warn occupants and staff about the work
  • Point out parking and an unloading spot

When something else is needed

Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:

  • Damp caused by condensation inside the building
  • Replacing glass or failed glazing units
  • Damaged frames that need replacing

If in doubt, phone 01277 525 020 or send photos by email and we’ll say what we think.

What we seal

  • Coping and flashing joints
  • Stone and brick facade joints
  • Shopfront frames
  • Window and door perimeters
  • Perimeter joints where frames meet the structure
  • Cladding panel joints

Work for main contractors and building owners

Building owners and managing agents use us on everything from one building to a spread of sites. Several sites can go on one quote, so there’s one set of paperwork to deal with.

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, and each stage is agreed with your contact.

After the work

Keep the joints in good shape with a few simple steps:

  • Share access with other external trades
  • Keep the sealant details on the building file
  • Add perimeter sealant to planned maintenance checks
  • Avoid patch repairs on failed facade joints

After heavy weather, check vulnerable elevations for signs of water inside. An early report usually means a small reseal rather than a bigger repair.

Building facade joints into a maintenance cycle avoids emergency repairs. Regular checks let you renew joints before water gets in instead of after the damage.
