Facade sealing for Boyden Gate sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Facade sealing in Boyden Gate

External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits, so frosty or damp mornings can hold work back. We build that into the programme and tell you if the forecast changes the plan. We work on cladding panel joints, shopfront frames and stone and brick facade joints, and the failures we’re asked to look at most are discoloured or dirty facade joints and gaps between rainscreen or cladding panels. Searching for sealant specialists in Boyden Gate? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

Construction in and around smaller places such as Boyden Gate is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant.

Diagnose, treat, sign off

On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work usually takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. If others near Boyden Gate need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  1. Access, site rules and timing are settled with the client up front.
  2. Weather and temperature are checked against the product’s limits.
  3. Each joint is cut out and the edges inspected.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. Once signed off, the work carries our 12-month guarantee.

Before we start on site

  • For older buildings, check the asbestos register before work
  • Have the specification and drawings to hand
  • Point out any areas we must not close

What sealant work can’t fix

Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:

  • Joints whose design needs changing by the specifier
  • Installing or repairing glazing systems
  • Providing access systems for the work

If in doubt, give us a call on 01277 525 020 or use the quote form and we will say what we think before you book.

Joints and surfaces we work on

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

General trades versus a specialist

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Questions we’re asked in Boyden Gate

Can you work at a site such as Chislet Business Park, by Boyden Gate?

Yes. Our area takes in Boyden Gate and its surroundings, with estates and business parks such as Chislet Business Park included. To start, just call 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

Does a coastal location like Boyden Gate affect which sealant is used?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Is your workmanship covered by a guarantee?

Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.

How do you choose the sealant?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Which sealant do you use on facades?

It depends on the joint, the substrate and any specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing and we follow the specified product.

Will you quote for a small job?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

Surface by surface

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 with a product suited to glazing perimeters.

Coping and flashing joints

Coping and flashing joints are included where sealant is the specified fix. They sit in the most exposed positions on the building.

Facade sealing in Boyden Gate: the local picture

Boyden Gate lies within about 3 miles of the sea. 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, Boyden Gate included, is lower than in many 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.

When units on a site such as Chislet Business Park (to the south-west of Boyden Gate) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. School extensions, at buildings such as Chislet Church of England Primary School, usually run to the summer holidays, mastic included.

Do you need facade sealing in Boyden Gate?

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.

Typical triggers for a call:

  • Gaps between rainscreen or cladding panels
  • Leaks at window and door perimeters
  • Perimeter sealant that has split or peeled away
  • Discoloured or dirty facade joints

Extensions at sites like Queen Victoria Memorial Hospital, 2.5 miles north-west of Boyden Gate, usually sit beside working departments, and the mastic follows strict access rules.

Questions to ask before you book

  • How long is the guarantee, and what does it include?
  • Whether their applicators hold CSCS cards
  • How joint depth will be controlled
  • What site paperwork they can supply

How to choose a sealant contractor

Leave it or put it right?

If access is already up for other work, resealing at the same time makes sense. Coordinating facade sealing with other external works avoids paying for access twice, which is often the biggest saving. For buildings around smaller places like Boyden Gate, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.

The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a quote once you have the details.
