Need facade sealing in Alkham?

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Looking after the joints

Regular inspection catches problems early. Specifically:

  • Brief window cleaners about newly sealed joints
  • Don’t wait for a second leak before calling
  • Note when each elevation was last resealed
  • Add perimeter sealant to planned maintenance checks

Record the sealant type and date on the building file. Future work can then match the product and colour without guesswork.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos, and if it’s suspected, we stop until it has been tested.

How we handle facade sealing in Alkham

Weather decides a lot in facade sealing. The sealant needs a dry joint and temperatures inside the maker’s limits. We build that into the programme and tell you if the forecast changes the plan. Site teams most often ask us about unsightly perimeter sealant on a visible elevation and facade joints cracked through the middle, across coping and flashing joints, stone and brick facade joints and window and door perimeters. A single leaking joint is often how a building in Alkham first comes to us: we look at the rest while we’re there and tell you what we find.

For a site near Alkham, 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.

A 12-month guarantee applies to all our work. If an installation problem shows up, call 01277 525 020 or email a schedule or drawings and we will arrange a return visit.

FAQs: Alkham

Will you plan work around the academic year at somewhere like University Centre Folkestone?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Can being near the sea in Alkham affect the sealant we need?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

Do we need an asbestos check before resealing?

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.

Can you work while the building is occupied?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

Will your applicators have CSCS cards?

Yes. If you need card details for site access, tell us and we will confirm them with the quote.

Are you insured?

Yes. We’re fully insured, including public liability cover.

What will the job cost?

That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we’ll price it properly.

Different surfaces, different methods

Render and coated surfaces

Rendered and painted facades need a sound edge for the sealant to bond to. Loose coatings are cleaned back first, and we will mention any edges that need repair.

Perimeter joints at frames and structure

Perimeter joints at frames often show their age first. We cut them out, prepare both faces and reseal to the specification using a sealant classified for that use.

Common problems we fix in Alkham

Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.

Any of the following is a good reason to get the joints checked over:

  • Old perimeter mastic that has dried out
  • Failed sealant on precast panel joints
  • Draughts around frames and panels
  • Damp patches beside frames after rain

Historic houses such as Acrise Place, 3.9 miles to the west of Alkham, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Before you book anyone

  • What site paperwork they can supply
  • Will failed sealant be removed rather than covered?
  • Who will actually carry out the work
  • Health and safety accreditation such as CHAS

How to choose a sealant contractor

General trades versus a specialist

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Facade sealing around Alkham: what changes locally

The sea is no more than about 3 miles from Alkham. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, and the sealant, primer and backing need choosing with that in mind. Rainfall across the South East, Alkham included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team.

Building work at universities like University Centre Folkestone, 4.1 miles south-west of Alkham, is often timed for the summer, mastic included. Hospital estates such as Buckland Hospital (to the east of Alkham) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

What sets the cost

Before we quote, we look at:

  • Travel to remote or island sites
  • Access and working height
  • Backing rod, priming and other preparation
  • Induction, permit and paperwork requirements

What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a quote when you’re ready.

Details that help us quote

It doesn’t need to be a full survey. These details are enough to start:

  • Whether an asbestos survey exists
  • Any specification or named product
  • The site address and postcode
  • How the joints are reached, and at what height

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Diagnose, treat, sign off

Tell us your site hours and access windows and we will plan around them. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Smaller jobs around Alkham can be grouped with others nearby. You will have a fixed quote before work starts.

  1. First we review photographs, 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. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. We walk the finished joints with you before handing over.
