Facade sealing in Newdigate

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

Common problems we fix in Newdigate

Three-sided adhesion is a classic installation fault. With no backing, the sealant is restrained and rips when the facade moves.

These are often picked up first by site or facilities staff:

  • Old perimeter mastic that has dried out
  • Cladding panel joints that have opened up
  • Perimeter sealant that has split or peeled away
  • Damp patches beside frames after rain

School extensions, at buildings such as Newdigate CofE Endowed Aided Infant School, typically run to the summer holidays, mastic included.

What your quote should include

  • Will RAMS and insurance details be available?
  • What level of public liability insurance do they hold?
  • Health and safety accreditation such as CHAS
  • How the joint faces will be prepared and primed

Choosing a commercial sealant contractor

Facade sealing in Newdigate, done properly

We seal window and door perimeters, cladding panel joints, external facade joints and perimeter joints where frames meet the structure on commercial buildings in Newdigate. Coping and flashing joints are included where sealant is the specified fix. The enquiries we see most involve failed seals around shopfront and entrance frames and sealant pulling away from frames or panels, on perimeter joints where frames meet the structure, coping and flashing joints and window and door perimeters. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Newdigate, that means joint design, primers and backing rod as standard.

For a site near Newdigate, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Drawings, photographs and the programme let us give a fixed quote.

A 12-month guarantee applies to all our work. Should something we installed fail, call the office on 01277 525 020 or email a schedule or drawings and we will come back to it.

Site staff or a sealant specialist?

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

How a job runs

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. If others near Newdigate need work, visits can be combined. You will have a fixed quote before work starts.

  1. We look at the joints, the drawings and the access before pricing.
  2. The old bead is cut away completely, not overlaid.
  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. 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

  • Tell us which areas need to stay in use
  • Move anything stored against the joints
  • Warn occupants and staff about the work

Questions we are asked in Newdigate

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

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 Newdigate too small for you to travel to?

No. Small places get the same service as large ones. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Are your applicators CSCS-carded?

Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.

Can you handle several sites?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

Will you quote for a small job?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

What about RAMS and site documents?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Can you work in cold or wet weather?

We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Frost and condensation on glass and steel are common on winter mornings, and we build that into the programme.

Contractors’ notes for Newdigate

Newdigate sits in one of the drier corners of the country, the South East. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, which is why external dates are agreed with the site manager. Newdigate is about 24 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes.

On a healthcare site such as Langley Green Hospital, 4.9 miles to the south-east of Newdigate, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Newdigate is about 5 miles south of Dorking, in Surrey. Anywhere in RH5, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Newdigate is one of 379 places we cover in Surrey for facade joints. We also cover London, some 24 miles away.

We cover the RH5 postcode districts for facade joints. We cover commercial and managed buildings on Church Road, Underhill Road and Village Street. Nearby places we also cover include Cudworth (1 mile east), Parkgate (1 mile north-east), Shellwood Cross (2 miles north), Russ Hill (2 miles south-east) and Nalderswood (3 miles north-east). Nearby towns on our patch include Guildford (14 miles north-west), Epsom (12 miles north), Horley (5 miles east), Redhill (7 miles north-east), Ewell (13 miles north) and Reigate (6 miles north-east).

Surface by surface

Coping and flashing joints

Sometimes the coping or flashing itself has failed. Where the issue isn’t the sealant, we say so.

Cladding panel joints

Where panels are sealed rather than open-jointed, the bead is part of the weather line. Failed runs are cut out and rebuilt end to end to the correct depth.

Honest limits

Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:

  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Arranging specialist high-level access, which is planned with the client
  • Joints too narrow for the movement they take, which need redesign

If in doubt, call the office on 01277 525 020 or send details through our quote form and we’ll say what we think.

What we seal

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