Different surfaces, different methods

Coping and flashing joints

Where the specification calls for sealant at copings or flashings, we can seal them. They sit in the most exposed positions on the building.

Precast concrete panels

Precast panel joints have to absorb thermal and structural movement. A sealant of the right movement class goes in over backing rod.

What we can’t put right

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Damaged frames that need replacing
  • Joints whose design needs changing by the specifier
  • Arranging specialist high-level access, which is planned with the client

Not sure which it is? You can call 01277 525 020 or email drawings and photos and we’ll tell you honestly.

Where we work in Beggar's Bush

  • Window and door perimeters
  • Coping and flashing joints
  • Cladding panel joints
  • Stone and brick facade joints

Beggar's Bush: questions and answers

Is Beggar's Bush off your patch?

No. Small places get the same service as large ones. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Can you take on a job at a hospital such as Heatherwood Hospital?

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

Will you quote for a small job?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

How long does a job like this take?

It depends on the scope, though a typical visit normally takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

Can you work on upper floors?

We agree access with the client at the start. Let us know what access is in place or planned, and we will price the work around it.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

Facade sealing in Beggar's Bush: the local picture

The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager. Beggar's Bush has a number of hotels close by, all within 2 miles. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.

University estates such as Imperial College Silwood Park Campus (to the north-west of Beggar's Bush) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. Work at a hotel such as Royal Berkshire Hotel (less than half a mile north-east of Beggar's Bush) tends to be programmed around bookings, mastic included.

Beggar's Bush is about 4 miles west of Egham, in Windsor and Maidenhead. Anywhere in SL5, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed.

Keeping the joints sound

Keep the joints in good shape with a few simple steps:

  • Don’t wait for a second leak before calling
  • Add perimeter sealant to planned maintenance checks
  • Brief window cleaners about newly sealed joints
  • Check the asbestos register before old mastic is disturbed

Let the new sealant cure before washing the facade or windows near it. Pressure washers and harsh cleaners can damage a fresh bead and tell your cleaning contractor.

Coordinate facade sealing with other external works. Sharing the access keeps the cost down.

Our process

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. For work around Beggar's Bush, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed in full and both faces cleaned back.
  4. Primer is applied where the maker specifies it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

Preparing the site

  • Tell us your opening times and when work is allowed
  • Send any specification or drawings in advance

What we’re called out for in Beggar's Bush

Product choice matters: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Most external joints call for a neutral-cure, facade-grade sealant.

Any of the following is a good reason to get the joints checked over:

  • Sealant pulling away from frames or panels
  • Unsightly perimeter sealant on a visible elevation
  • Previous reseals run over old sealant
  • Perimeter joints where frames meet the structure

Extensions at sites like Heatherwood Hospital, 2.1 miles west of Beggar's Bush, normally sit beside working departments, and the mastic follows strict access rules.

Comparing quotes

  • Whether old or failed sealant will be cut out, not overlaid
  • Health and safety accreditation such as CHAS
  • Whether their applicators hold CSCS cards
  • Their approach to joint depth and backing
