Facade sealing in Coleshill

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Facade sealing for commercial buildings in Coleshill

A good facade joint depends on design as much as product. Joint width needs to match how far the joint moves and how far the sealant can stretch, while rod fixes the depth and stops the bead sticking to the rear, often at around 2:1 width to depth, as the manufacturer advises. We work on stone and brick facade joints, coping and flashing joints and shopfront frames, and what we’re called in for most is sealant pulling away from frames or panels and leaks at window and door perimeters. Whether you call it commercial sealant work, mastic application or joint sealing, in Coleshill it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Conversions of older rural buildings near smaller places such as Coleshill bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Diagnose, treat, sign off

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, and the work typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather. For a building around Coleshill, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. Product choice follows the joint’s movement and substrate.
  3. Failed beads are removed in full and both faces cleaned back.
  4. Primer is applied where the maker specifies it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. We go over the completed work with you before leaving.

Why act early in Coleshill

Scaffold or access already on site makes resealing much simpler. Coordinating facade sealing with other external works avoids paying for access twice, saving a second set-up. Converted and older buildings near places like Coleshill tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

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.

Why clients in Coleshill choose us

  • Fixed quotes based on photographs, drawings or a visit
  • CHAS accredited contractor
  • Products installed to the manufacturer’s instructions
  • Over 20 years of commercial sealing

Facades, frames and programmes in Coleshill

A 2-mile radius around Coleshill takes in several hotels. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight. 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, so the external programme keeps a little slack.

For a contractor at a hotel such as Kings Arms Hotel, 1.4 miles to the north-east of Coleshill, the mastic often has to be finished before a reopening date. For contractors at a school such as Coleshill Church of England Infant School, sealing has to be finished before term starts. When units on a site such as St. Georges Industrial Estate, 2.4 miles to the north-east of Coleshill, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Coleshill: questions and answers

Is a smaller place like Coleshill outside your area?

Not at all. Coleshill is within our area. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Can you work at a site such as St. Georges Industrial Estate, by Coleshill?

Yes. Our area takes in Coleshill and its surroundings, with estates and business parks such as St. Georges Industrial Estate included. Photos and a short description are enough for a first look.

Do you install glazing systems?

No. That work needs a glazing specialist. We reseal window perimeters, panel joints and frame-to-structure perimeters on commercial buildings.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Are you CHAS accredited and on Constructionline?

Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.

Do you run new sealant over the existing bead?

No. New sealant won’t hold on old sealant, so the old bead is cut away. That is what makes the new joint last.

Can you handle several sites?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

What we can’t put right

Some faults sit outside our scope, and we say so rather than covering them up:

  • Joints too narrow for the movement they take, which need redesign
  • Water getting in through cracked render or porous masonry
  • Specialist high-level access methods

If in doubt, call the office on 01277 525 020 or send details through our quote form and we’ll say what we think.

Surfaces we seal

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

What the job involves on each 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.

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.

When to bring in a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
