Facade sealing in Gatton

We don’t install glazing systems or replace glass. We handle the sealant joints that surround those elements: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds. We work on perimeter joints where frames meet the structure, cladding panel joints and stone and brick facade joints, and what we’re called in for most is leaks at window and door perimeters and gaps between rainscreen or cladding panels. Whoever orders the work in Gatton, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

For a site near Gatton, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Send drawings or photos and the programme and we will quote to suit.

A 12-month guarantee applies to all our work in Surrey. If an installation problem shows up, ring 01277 525 020 or use the quote form and we’ll arrange a return visit.

Mastic packages on Gatton sites

Gatton has a number of hotels close by, all within 2 miles. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight. Gatton sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team.

For contractors at a college like Reigate College, which lies south-west of Gatton, perimeters and internal sealant are timed for the holidays. Extensions at sites like East Surrey Hospital, 3.1 miles to the south of Gatton, typically sit beside working departments, and the mastic follows strict access rules.

Gatton is about 2 miles north of Redhill, in Surrey. We cover Gatton, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. 379 places across Surrey fall within our area, Gatton among them. London is covered too, around 17 miles from Gatton.

Commercial sites across RH2 and RH1 are covered. Buildings on Rocky Lane and Gatton Bottom are within our area. Sites close to Gatton are covered too, including South Merstham (1 mile east), Holmethorpe (1 mile south-east), Merstham (1 mile north-east), Mugswell (1 mile north-west) and Redhill (2 miles south). Further afield, our area takes in Epsom (7 miles north-west), Horley (6 miles south), Ewell (7 miles north-west), Walton-on-Thames (13 miles north-west), Caterham (4 miles north-east) and Dorking (7 miles west).

For managing agents and facilities managers

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.

On site: what to expect

Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Jobs in and around smaller places like Gatton are usually planned as a single visit, so we ask for photos 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. 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. 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. We walk the finished joints with you before handing over.

Getting the site ready

  • Confirm the product named in the specification
  • Move anything stored against the joints
  • Tell us which areas need to stay in use

Ask for a quote

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or call the office on 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.

When something else is needed

We check first that sealant really is the fix. It won’t put right:

  • Providing access systems for the work
  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Movement beyond what any sealant can handle

If you’re not sure, just call 01277 525 020 or email us and we’ll give you a straight answer before you book.

Joints and surfaces we work on

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

After the work

Problems stay small when the joints are checked regularly. In particular:

  • Record the product and colour used on each elevation
  • Avoid harsh cleaners on facade sealant
  • Avoid patch repairs on failed facade joints
  • Check the asbestos register before old mastic is disturbed

Keep a note of which product went in and when. Future work can then match the product and colour.

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

Common problems we fix in Gatton

When sealant lets go of a frame or panel, the cause is often the preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond, and movement soon pulls it away.

Clients normally get in touch after noticing something like this:

  • Draughts around frames and panels
  • Failed sealant on precast panel joints
  • Discoloured or dirty facade joints
  • Weathered joints at frame-to-structure perimeters

For contractors refurbishing units at places like Kingsfield Business Centre (2.1 miles south of Gatton), the mastic covers cladding panels, roller-door and window perimeters.

What your quote should include

  • Are they CHAS accredited or on Constructionline?
  • Proof of insurance
  • Who will actually carry out the work
  • Whether old or failed sealant will be cut out, not overlaid

Questions to ask before you appoint anyone

Questions we are asked in Gatton

Can work at a site such as Reigate College fit around teaching?

Yes. We plan campus work around teaching, exams and residence turnarounds. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Is Gatton too small for you to travel to?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Can you quote from photos?

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

Does the weather affect the work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Will rain stop the work?

Year-round work is possible as long as joints are dry and temperatures suit the product. Frost and condensation on glass and steel are common on winter mornings.

How do you choose the sealant?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

What site paperwork can you supply?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

When to bring in a specialist

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
