Facade sealing for Englefield Green sites

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

Facade sealing in Englefield Green, done properly

Most facade joint failures trace back to the joint, not just the sealant. The width has to suit the expected movement and the sealant’s movement capability, and closed-cell rod sets the depth, keeping the bond to two faces, often at around 2:1 width to depth, as the manufacturer advises. If you are dealing with old perimeter mastic that has dried out and cladding panel joints that have opened up, we can put it right, whatever the surface. Whoever orders the work in Englefield Green, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

In a smaller place such as Englefield Green, construction tends to mean small housing schemes, conversions and extensions to community buildings. Even a small site needs its perimeter and facade joints sized, backed and sealed properly.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, give us a call on 01277 525 020 or email a schedule or drawings and we’ll come back to it.

How the quote is worked out

What shapes the price:

  • Travel to remote or island sites
  • Access and working height
  • How much there is to seal
  • Which sealant the job calls for

We don’t publish prices, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.

Sending details for a quote

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

  • Whether the building will be occupied during the work
  • Rough lengths or quantities, or drawings if you have them
  • Clear photos of the problem areas
  • Where the site is, with the postcode

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, call 01277 525 020 or send photos by email.

Building and refurbishing in Englefield Green

There are a good number of hotels within about 2 miles of Englefield Green. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. At about 21 miles from central London, Englefield Green is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme.

Recladding or extending a unit at a site like The Green Business Centre (1.7 miles east of Englefield Green) brings panel joints and frame perimeters into the programme. Projects at colleges like Strode's College, 0.9 miles east of Englefield Green, tend to run to term dates, so the mastic is planned tightly.

How the job changes by surface

Cladding panel joints

On sealed panel systems, every joint keeps water out. Failed runs are cut out and rebuilt end to end.

Precast concrete panels

Precast panel joints have to absorb thermal and structural movement. A sealant of the right movement class goes in over backing rod with primer where the product requires it.

Signs you need facade sealing in Englefield Green

Most facade joints fail through age and weathering. UV and weather harden the sealant until it can’t stretch with the building, and cracks or adhesion loss follow.

Site and facilities staff are often the first to spot these:

  • Unsightly perimeter sealant on a visible elevation
  • Gaps between rainscreen or cladding panels
  • Old perimeter mastic that has dried out
  • Weathered joints at frame-to-structure perimeters

Building work at universities like Royal Holloway University, less than half a mile south-east of Englefield Green, is often timed for the summer, mastic included.

Questions to ask before you appoint anyone

Why act early in Englefield Green

Failed joints let in more than water: draughts around frames add to heating costs and complaints. Resealing deals with the draught as well as the leak. Small buildings around Englefield Green suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

When it isn’t the sealant

Before quoting, we check that sealant is the right answer. It won’t put right:

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

If in doubt, ring 01277 525 020 or email us and we’ll say what we think.

Joints and surfaces we work on

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

Our process

Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. If neighbouring businesses or buildings around Englefield Green need work too, visits can be combined. Tell us your site hours and we’ll plan around them.

  1. We look at the joints, the drawings and the access before pricing.
  2. Failed sealant is cut out along its full length.
  3. Both faces are cleaned and, where the product needs it, primed.
  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. The completed runs are checked with you, then the 12-month guarantee applies.

What we need from you

  • Share your working hours and any access restrictions
  • Let building users know which areas are affected
  • Share the asbestos register for older buildings

Advice

Common questions from Englefield Green clients

Can you work around term dates at a campus such as Royal Holloway University?

Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Is a hospital such as King Edward VII Hospital somewhere you can work?

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

Can you send site paperwork?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

Is Englefield Green in your area?

Yes. We cover Englefield Green, and the simplest way to start is to speak to us on 01277 525 020 or email a schedule or drawings.

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, and if anything is suspected, we stop until it’s tested. Removal of asbestos isn’t something we do.

Will you come and look before quoting?

Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit.

Do you seal on top of existing sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
