Facade sealing in Brompton

Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters, using sealants classified for facade or glazing use. The enquiries we see most involve perimeter sealant that has split or peeled away and gaps between rainscreen or cladding panels, across cladding panel joints, shopfront frames and window and door perimeters. Searching for sealant specialists in Brompton? Mastic Doctor has worked for contractors, FMs and building owners since 2005.

For a contractor on a smaller site near Brompton, one mastic visit at the right stage saves return trips. Tell us when scaffold comes down and when decoration finishes, and we’ll plan around those stages.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Facade sealing in Brompton: the local picture

Brompton is within about 2 miles of the coast. Coastal exposure means perimeter and cladding joints work harder than on an inland job, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Brompton has a good number of hotels close by, all within 2 miles. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.

Further education sites such as MidKent College Gillingham Campus (to the north-east of Brompton) are extended and refurbished from time to time, with mastic often programmed into the summer break. For a contractor at a hotel such as King Charles Hotel, under half a mile north-east of Brompton, the mastic often has to be finished before a reopening date. On a healthcare site such as Medway Maritime Hospital, 0.8 miles south-east of Brompton, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Brompton is about 1 mile east of Rochester, in Medway. Commercial clients in Brompton can call on us for facade joints, as part of our coverage of Medway. 54 places across Medway fall within our area, including Brompton. There’s a separate page for London, about 28 miles away.

How the quote is worked out

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • Whether the work must be split into stages
  • The site’s rules and procedures
  • Which sealant the job calls for
  • How much existing material needs removing

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Sending details for a quote

The more we know, the firmer the quote. Helpful details to send:

  • The product your specification calls for
  • Any dates the work must fit around
  • What the building is and how it’s used
  • Photos of the joints, close up and from further back

Let us know the site, the scope and your timescale, and we will put a fixed quote together. The easiest way is to speak to us on 01277 525 020 or email drawings and photos.

Brompton: questions and answers

Is a smaller place like Brompton outside your area?

Not at all. Brompton is within our area. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Do you cover business parks and estates near Brompton, such as Railway Street Industrial Park?

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

Does weather matter for sealant work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also call the office on 01277 525 020 or send details through our quote form. Include photographs or drawings if you have them.

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

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Can you handle several sites?

Yes. A group of buildings can go on one quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

Do you provide access for facade work?

Access is planned with you before we quote. Tell us about access: existing scaffold, what you are arranging and any site restrictions, and the quote will reflect it.

From enquiry to sign-off

Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. What matters most for a job in Brompton is a clear list of what needs doing, so send photos of each area. You will then get a fixed price for the work.

  1. Access, site rules and timing are settled with the client up front.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. We remove the old bead and check the edges are sound.
  4. Faces are cleaned, primed where needed and backed.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. We hand over with our 12-month workmanship guarantee.

What we need from you

  • Tell staff and tenants when we’ll be in
  • Explain the parking and delivery arrangements
  • Share the asbestos register for older buildings

What sealant work can’t fix

Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:

  • Joints too narrow for the movement they take, which need redesign
  • Replacing glass or failed glazing units
  • Render or concrete edges that have broken away

Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.

Joints and surfaces we work on

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

What the job involves on each surface

Render and coated surfaces

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

Coping and flashing joints

Not every coping or flashing leak is a sealant problem. We tell you if the fix is a roofing or metalwork job rather than a reseal.

General trades versus a specialist

Redoing a failed joint normally 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.

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Why it’s worth doing now in Brompton

Every shower drives water through a split perimeter bead. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing now costs less than repairing interiors later. In a smaller place such as Brompton, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.
