About our facade sealing in Furze Platt

Facade sealants sit in the sun, rain and frost every day, and they wear out over time. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When it fails, the whole bead is cut away and the joint rebuilt. If you are dealing with perimeter sealant that has split or peeled away and weathered facade joints that have lost their grip, we can help, whatever the surface. One point of contact handles commercial sealant work in Furze Platt from the first photos to the final walk-round, for single jobs and planned programmes alike.

Around places like Furze Platt, a lot of construction is the conversion of older buildings, which leaves joints between old walls and new frames that need a sealant able to take the movement, in a colour the planners or architect are happy with.

A 12-month guarantee applies to all our work in Windsor and Maidenhead. Should something we installed fail, ring 01277 525 020 or email us and we’ll come back to it.

Diagnose, treat, sign off

We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For a job in Furze Platt, the main thing is a clear picture of the work, so send photographs of each area. You’ll then get a fixed price for the work.

  1. First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. Failed sealant is cut out along its full length.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. We walk the finished joints with you before handing over.

Getting the site ready

  • Send asbestos survey details if the building is pre-2000
  • Warn occupants and staff about the work
  • Send any specification or drawings in advance

What happens if it’s left?

A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Water through a failed joint rarely stays where it starts, often turning up far from the joint. Small buildings around Furze Platt suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.

The product called for affects the cost, and so does the preparation. Access, phasing and site rules also count.

Why choose Mastic Doctor in Furze Platt

  • 12-month guarantee on workmanship
  • Old sealant cut out, never sealed over
  • CHAS accredited contractor
  • Colours confirmed for the specified product

See our cost guide or our accreditations and insurance.

Site staff or a sealant specialist?

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

How the job changes by surface

Cladding panel joints

Joints between cladding panels open and close with temperature. We use a product rated for the movement and suited to the panel surface, as the specification sets out.

Render and coated surfaces

Where the joint will be painted over, a paintable hybrid or PU sealant may suit. The choice depends on the specification and finish.

Mastic packages on Furze Platt sites

The area within 2 miles of Furze Platt holds a good number of hotels. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included. At about 28 miles from central London, Furze Platt is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes.

For a contractor at a hotel such as Bear Hotel, 1.2 miles south-east of Furze Platt, the mastic often has to be finished before a reopening date. On a healthcare site such as St Mark's Hospital, which lies south-west of Furze Platt, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. For contractors at a school such as Furze Platt Senior School, sealing has to be finished before term starts.

Questions we’re asked in Furze Platt

Is a hospital such as St Mark's Hospital somewhere you can work?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Could you schedule work at a campus like Berkshire College of Agriculture for the vacation?

Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards.

Do you guarantee your work?

Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.

Can you quote from photos?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.

How long before the joints can be used?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

How is access to upper-level joints handled?

That varies with the building and the access on offer. When you give us a call on 01277 525 020 or email us, describe the access, and we will plan the work with you.

Looking after the joints

A few simple habits keep the new joints working:

  • Keep sills, gutters and drainage paths clear
  • Keep the sealant details on the building file
  • Confirm the survey covers external sealants in older buildings
  • Avoid harsh cleaners on facade sealant

Hold back any cleaning crew until the joints have had their stated cure time. Pressure washers and harsh cleaners can damage a fresh bead, so brief your window cleaners.

Don’t wait for a full elevation to fail. A few metres resealed promptly can stop water damage spreading inside the building.
