About our facade sealing in Hildenborough

External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits, and cold, damp starts can delay work. We build that into the programme and tell you if the forecast changes the plan. We work on stone and brick facade joints, perimeter joints where frames meet the structure and shopfront frames, and the failures we’re asked to look at most are weathered joints at frame-to-structure perimeters and draughts around frames and panels. For commercial sealant work in Hildenborough, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

For a site near Hildenborough, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Drawings, photos and the programme let us give a fixed quote.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, call 01277 525 020 or use the quote form and we’ll arrange a return visit.

Why deal with it now?

Every shower drives water through a split perimeter bead. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing early costs far less than repairing what the water reaches. Around Hildenborough, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we’ll quote for the lot.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Why choose Mastic Doctor in Hildenborough

  • Joints cleaned back to sound surfaces
  • Our applicators hold CSCS cards
  • Standard and matched colours in many product ranges
  • A Constructionline member, so easy to vet

Read how commercial sealant jobs are priced or how we’re accredited.

How the quote is worked out

These are the things that shape the price:

  • How accessible the joints are
  • Travel to remote or island sites
  • Site requirements such as inductions and permits
  • Specialist products, such as fire-rated or hygienic sealants

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.

Details that help us quote

To price the job accurately, we need to understand the site. Useful things to include:

  • Photos of the joints, close up and from further back
  • Any dates the work must fit around
  • What the building is and how it’s used
  • The site address and postcode

A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or give us a call on 01277 525 020 or email the details over if you’d rather talk the job through.

What sealant work can’t fix

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Cracked or spalling substrates that need repair before sealing
  • Replacing glass or failed glazing units
  • Damp caused by condensation inside the building

If in doubt, phone 01277 525 020 or email drawings and photos and we will say what we think.

Surfaces we seal

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

Your questions answered

Is Hildenborough too small for you to travel to?

No. Small places get the same service as large ones. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Will you plan work around the academic year at somewhere like University of Kent - Tonbridge?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Do you run new sealant over the existing bead?

No. Overlaying is a shortcut that peels away quickly. We remove the failed sealant, clean the faces, set the depth and reseal.

Do you need to see the site first?

It depends on the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.

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

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

Is old mastic on our building likely to contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. The dutyholder’s asbestos register should be checked first. We don’t remove asbestos-containing materials.

When to bring in a specialist

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.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

On site: what to expect

Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. If others near Hildenborough need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. We look at the joints, the drawings and the access before pricing.
  2. The old bead is cut away completely, not overlaid.
  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. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

Preparing the site

  • Tell staff and tenants when we will be in
  • For older buildings, check the asbestos register before work
  • Clear stock, furniture or equipment away from the joints

Building and refurbishing in Hildenborough

The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager. At about 24 miles from central London, Hildenborough 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.

Further education sites such as West Kent College (2.3 miles south of Hildenborough) are extended and refurbished from time to time, with mastic often programmed into the summer break. University estates such as University of Kent - Tonbridge (to the south-east of Hildenborough) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. Projects at schools like Hildenborough Church of England Primary School work to term dates, so mastic is programmed tightly.

Aftercare for building managers

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

  • Report water ingress at frames as soon as it shows
  • Note when each elevation was last resealed
  • Inspect facade joints on a regular cycle
  • Brief window cleaners about newly sealed joints

Look at perimeter and panel joints as part of routine building checks. Signs to look for are cracking, edges lifting, chalking and stiffness.

Deal with sections that fail early as soon as they show. Small repairs stop small leaks becoming large ones inside the building.
