Facade sealing for Thorpe Green sites

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

How the job changes by surface

Cladding panel joints

Panel joints on cladding and rainscreen systems take movement every day. We use a product rated for the movement and suited to the panel surface, as the specification sets out.

Window and door perimeters

Perimeter joints move as frames expand and contract in the sun. The rod limits depth, leaving the bead able to flex without tearing.

Facade sealing in Thorpe Green

Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds with products suited to facade or glazing perimeter joints. If you are dealing with air leaks through failed facade joints and failed seals around shopfront and entrance frames, we can put it right, on cladding panel joints, coping and flashing joints and window and door perimeters alike. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Thorpe Green is the same: the right product in a properly prepared joint.

Construction in and around smaller places such as Thorpe Green is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Your questions answered

Can you work at a site such as Egham Business Park, by Thorpe Green?

Yes. Our area takes in Thorpe Green and its surroundings, with estates and business parks such as Egham Business Park included. A few photos and the unit address let us price the work.

Is a hospital such as St Peter's Hospital somewhere you can work?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Do you need to see the site first?

It depends on the job. Simple work can often be priced from photos, and bigger or more complex jobs normally get a visit.

How long do sealant joints last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards.

How long does a job like this take?

We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.

When it isn’t the sealant

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Damaged frames that need replacing
  • Arranging specialist high-level access, which is planned with the client
  • Replacing glass or failed glazing units

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

Where we work in Thorpe Green

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

General trades versus a specialist

Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Building and refurbishing in Thorpe Green

At about 20 miles from central London, Thorpe Green is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme. A number of hotels sit less than 2 miles from Thorpe Green. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight.

University estates such as Royal Holloway University (1.8 miles north-west of Thorpe Green) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. Units on estates such as Egham Business Park (0.9 miles north-east of Thorpe Green) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. When a college such as Strode's College (2.1 miles north of Thorpe Green) builds or refurbishes, the mastic package typically has to fit around students and staff.

Owners, agents and contractors

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

From enquiry to sign-off

Before we leave any area, we remove the tape, clean down and inspect every joint with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. Rural sites near Thorpe Green may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full.
  4. Primer goes on where the product data asks for it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. We go over the completed work with you before leaving.

Preparing the site

  • Confirm the product named in the specification
  • Tell us which areas need to stay in use
  • Tell us what induction or permit system the site runs
