Facade sealing across Farleigh

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Facade sealing in Farleigh

Facade joints are the line of defence between the weather and the building fabric. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. We work on window and door perimeters, stone and brick facade joints and perimeter joints where frames meet the structure, and the usual reasons a site gets in touch are leaks at window and door perimeters and new sealant peeling off old mastic. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Farleigh is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Sites around smaller places like Farleigh can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Drawings, photographs and the programme let us give a fixed quote.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Your questions answered

Will you plan work around the academic year at somewhere like John Ruskin College?

Yes. Education sites typically 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.

Do you take on work at healthcare sites like Warlingham Park Hospital?

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

Which sealant will you use?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

What do you charge?

Every job gets its own fixed quote. To get one, speak to us on 01277 525 020 or email us.

Is it okay to overlay old mastic?

No. Overlaying is a shortcut that peels away quickly. We remove the failed sealant, clean the faces, set the depth and reseal.

Do you replace windows or glass?

No. A glazing contractor handles that. What we seal are the joints around frames and panels across the facade.

Is your workmanship covered by a guarantee?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

Honest limits

Being straight saves everyone time. Fresh joints won’t solve:

  • Water getting in through cracked render or porous masonry
  • Installing or repairing glazing systems
  • Arranging specialist high-level access, which is planned with the client

Not sure which it is? You can phone 01277 525 020 or send details through our quote form and we will tell you honestly.

Surfaces we seal

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

What sets the cost

What shapes the price:

  • Whether the work must be split into stages
  • How much there is to seal
  • Joint width, depth and condition
  • Access and working height

Pricing facade joints depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

What to include in your enquiry

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

  • When you need the work done
  • Photos of the joints, close up and from further back
  • The type of building and who uses it
  • Approximate linear metres or a joint schedule

For a fixed quote, ring 01277 525 020 or send photos by email, telling us the site location and the nature of the job. You can also send details through our quote form.

Facades, frames and programmes in Farleigh

Farleigh is about 12 miles from central London. 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. Rainfall across the South East, Farleigh included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack.

Older buildings in the area around Farleigh, such as Addington Palace, 2.2 miles north of Farleigh, need care when sealed: the product has to suit soft or historic materials. For contractors at a college like John Ruskin College, 1.7 miles north of Farleigh, perimeters and internal sealant are timed for the holidays. School extensions, at buildings such as Meridian High School, normally run to the summer holidays, mastic included.

Farleigh is about 4 miles north-east of Caterham, in Surrey. Our applicators travel to Farleigh for work on facade joints. 379 places across Surrey fall within our area, Farleigh among them. Sites around London have their own page, roughly 12 miles from Farleigh.

How a job runs

Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. If others near Farleigh need work, visits can be combined. A fixed quote is given before anything starts.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. Failed sealant is cut out along its full length.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. We walk the finished joints with you before handing over.

Before we start on site

  • Tell us what induction or permit system the site runs
  • Let building users know which areas are affected
  • Move anything stored against the joints

Advice

Doing it in-house

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Redoing a failed joint typically costs more than getting it right at the outset, 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.

How the job changes 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.

Window and door perimeters

Aluminium, PVC-U and timber frames each have their own preparation needs. We clean and prime to the sealant maker’s guidance for each surface.

Why act early in Farleigh

Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Leaks travel along the structure, often turning up far from the joint. Around Farleigh, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we will quote for the lot.

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.
