Facade sealing for commercial buildings in East Malling

External joints face UV, rain, temperature swings and building movement all year, so they don’t last indefinitely. 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. We work on coping and flashing joints, shopfront frames and stone and brick facade joints, and the usual reasons a site gets in touch are hard, chalky sealant that no longer flexes and staining on stone next to old sealant. Facilities teams, main contractors and managing agents in East Malling tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

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

We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

What happens if it’s left?

Leaving failed perimeter sealant also makes the eventual job bigger: wet edges break down, so repairs may be needed before resealing. Acting at the first sign of splitting keeps the fix simple. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Surface by surface

Window and door perimeters

Frame materials vary, and so does the preparation. We clean and prime to the sealant maker’s guidance for each surface.

Render and coated surfaces

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

What we can’t put right

Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:

  • Water getting in through cracked render or porous masonry
  • Arranging specialist high-level access, which is planned with the client
  • Work on the window or framing system itself

If in doubt, speak to us on 01277 525 020 or send photos by email and we will say what we think before you book.

What we seal

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

Should maintenance staff do it?

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

What affects the price in East Malling

A fixed quote reflects the actual work. It takes account of:

  • Specialist products, such as fire-rated or hygienic sealants
  • How accessible the joints are
  • Induction, permit and paperwork requirements
  • Working within restricted access windows

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

Before you send an enquiry

It doesn’t need to be a full survey. A few details are enough to get going:

  • The site address and postcode
  • Anything awkward about access or site hours
  • Any dates the work must fit around
  • The type of building and who uses it

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, call the office on 01277 525 020 or email a schedule or drawings.

Your questions answered

Does your area include sites such as New Hythe Business Park, near East Malling?

Yes, sites like New Hythe Business Park are within our area, along with the rest of East Malling. Send details of the unit and the work through our quote form for a quick quote.

Can you work on a hospital site such as Maidstone Hospital?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

How many days will you need on site?

It depends on the scope, but the work typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators.

Are you insured?

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

Is it okay to overlay old mastic?

No. New sealant won’t hold on old sealant, so the old bead is cut away. Nothing else gives a bond that lasts.

Do you provide access for facade work?

We agree access with the client at the start. Let us know what access is in place or planned, and the quote will reflect it.

From enquiry to sign-off

At the end of each section, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. For a site in East Malling, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.

  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. 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.

Getting the site ready

  • Warn occupants and staff about the work
  • Point out parking and an unloading spot
  • Move anything stored against the joints

Ask for a quote

Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
