About our facade sealing in Berwick

We don’t install glazing systems or replace glass. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters. Site teams most often ask us about previous reseals run over old sealant and failed sealant on precast panel joints, on perimeter joints where frames meet the structure, stone and brick facade joints and shopfront frames. Facilities teams, main contractors and managing agents in Berwick tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Around smaller places like Berwick, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Your questions answered

Is a smaller place like Berwick outside your area?

No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Will you fit the mastic around our build programme in Berwick?

Yes, we work to the programme and the sequence the site sets. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Is old mastic on our building likely to contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Check the asbestos register or survey before it is disturbed; if it’s suspected, work stops until it has been tested. Removal of asbestos isn’t something we do.

Can one quote cover more than one building?

Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.

Who decides which product is used?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

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

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

How do I request a quote?

The quote form is the simplest route, though you can also ring 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.

What we can’t put right

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • Specialist high-level access methods
  • Damp caused by condensation inside the building
  • Joints too narrow for the movement they take, which need redesign

Not sure which it is? You can call 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.

Where we work in Berwick

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

Doing it in-house

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. For that reason, many FMs and contractors use a sealant specialist from the outset.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Aftercare for building managers

Regular inspection catches problems early. Specifically:

  • Plan facade sealing alongside redecoration
  • Avoid harsh cleaners on facade sealant
  • Record the product and colour used on each elevation
  • Check that rainwater leaves the facade the way it was designed to

Record the sealant type and date on the building file. It helps when matching repairs or planning the next reseal across the elevation.

Get the joint design right when resealing: the right width, backing rod and a sealant with enough movement capability. Repeating a faulty detail just repeats the failure.

What the job involves on each surface

Window and door perimeters

Aluminium, PVC-U and timber frames each have their own preparation needs. Primer goes on where the manufacturer specifies it for that substrate.

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.

Building and refurbishing in Berwick

With the shore within about 2 miles, Berwick counts as a coastal location. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, so we check the specified product suits the exposure before the first bead. Rainfall across the South East, Berwick included, is lower than in many parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager.

When a school such as Lympne Church of England Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. Older buildings in the area around Berwick, such as Westenhanger Castle (0.9 miles north of Berwick), need care when sealed: the product has to suit soft or historic materials.

Cost factors for facade joints

Your fixed quote is built from the real scope. It takes account of:

  • Whether the work must be split into stages
  • Induction, permit and paperwork requirements
  • Access and working height
  • Backing rod, priming and other preparation

A quote for facade joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

Before you send an enquiry

The more we know, the firmer the quote. When you get in touch, include:

  • A wide shot and a close-up of the area
  • Where the site is, with the postcode
  • The product your specification calls for
  • Your programme or deadline

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

Our process

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a building around Berwick, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full.
  4. Primer goes on where the product data asks for it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

What we need from you

  • Send any specification or drawings in advance
  • Point out parking and an unloading spot
  • Flag any permit to work we’ll need
