Facade sealing across Gomshall

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

Our process

On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, and the work typically takes a day or two for a few elevations, and longer where access has to be moved around the building. Jobs in and around smaller places like Gomshall are typically planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. The old bead is cut away completely, not overlaid.
  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. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

Before we start on site

  • Have the specification and drawings to hand
  • Point out any areas we must not close
  • Flag any permit to work we will need

Quotes

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, call 01277 525 020 or use the quote form.

About our facade sealing in Gomshall

We seal window and door perimeters, cladding panel joints, external facade joints and perimeter joints where frames meet the structure for clients around Gomshall. Coping and flashing joints are included where sealant is the specified fix. If you have unsightly perimeter sealant on a visible elevation and old perimeter mastic that has dried out, we can put it right, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Gomshall, that means joint design, primers and backing rod as standard.

Around smaller places like Gomshall, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Honest limits

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Work on the window or framing system itself
  • Damaged frames that need replacing
  • Leaks from roofs, gutters or failed flashings rather than sealant joints

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

Surfaces we seal

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

New build and refits around Gomshall

Gomshall is about 25 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes. Gomshall sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team.

On a healthcare site such as St. Luke’s Hospital (4.9 miles west of Gomshall), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Older buildings in the area around Gomshall, such as Hatchlands Park, 2.9 miles to the north of Gomshall, need care when sealed: the product has to suit soft or historic materials. School extensions, at buildings such as Shere CofE Aided Infant School, normally run to the summer holidays, mastic included.

Gomshall is about 5 miles west of Dorking, in Surrey. Businesses, contractors and managing agents in Gomshall use us for work on facade joints, as part of our coverage of Surrey. We work across 379 places in Surrey, large and small. We also cover London, some 25 miles away.

Questions we’re asked in Gomshall

Can you work to our programme on a site in or near Gomshall?

Yes. Send the programme and drawings, and we’ll plan the mastic to suit the stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Is a smaller place like Gomshall outside your area?

No. Places such as Gomshall are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

Do you seal on top of existing sealant?

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

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

How do I request a quote?

There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.

Will you come and look before quoting?

That depends on the size and complexity of the job. Simple work can often be priced from photographs, and bigger or more complex jobs normally get a visit.

Looking after the joints

To get the most from the new sealant:

  • Note when each elevation was last resealed
  • Avoid harsh cleaners on facade sealant
  • Investigate damp beside windows promptly
  • Inspect facade joints on a regular cycle

Hold back any cleaning crew until the joints have had their stated cure time. Keep high-pressure jets and strong chemicals away from new sealant and tell your cleaning contractor.

Building facade joints into a maintenance cycle avoids emergency repairs. Inspect regularly and reseal sections as they start to fail.

What affects the price in Gomshall

A fixed quote reflects the actual work. It takes account of:

  • Any access equipment needed
  • Induction, permit and paperwork requirements
  • Joint width, depth and condition
  • Removal of failed or old sealant

What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.

What we need to price the job

Whether it’s one area or a whole building, the same details help:

  • Anything awkward about access or site hours
  • The asbestos register, for older buildings
  • A wide shot and a close-up of the area
  • Any specification or named product

Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. The easiest way is to phone 01277 525 020 or email drawings and photos.

How the job changes by surface

Perimeter joints at frames and structure

The joint around a framed system, where it meets the structure, needs sealant. Our work is that perimeter joint.

Cladding panel joints

Where panels are sealed rather than open-jointed, the bead is part of the weather line. We cut out failed joints along their full length and rebuild them.
