Facade sealing across Egham Hythe

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

What we can’t put right

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Joints too narrow for the movement they take, which need redesign
  • Work on the window or framing system itself

If in doubt, call 01277 525 020 or use the quote form and we’ll say what we think.

What we seal

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

How we handle facade sealing in Egham Hythe

Facade joints are the line of defence between the weather and the building fabric. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We remove failed sealant and install a new bead chosen for the joint and how far it moves. Site teams most often ask us about failed seals around shopfront and entrance frames and draughts around frames and panels, across cladding panel joints, stone and brick facade joints and shopfront frames. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Egham Hythe is the same: the right product in a properly prepared joint.

In a smaller place such as Egham Hythe, construction tends to mean small housing schemes, conversions and extensions to community buildings. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.

Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

Different surfaces, different methods

Cladding panel joints

On sealed panel systems, every joint keeps water out. Failed runs are cut out and rebuilt end to end with backing and a facade-grade sealant.

Coping and flashing joints

Coping and flashing joints are included where sealant is the specified fix. They sit in the most exposed positions on the building, so preparation and product choice matter.

Looking after the joints

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

  • Check the asbestos register before old mastic is disturbed
  • Inspect facade joints on a regular cycle
  • Report water ingress at frames as soon as it shows
  • Check that rainwater leaves the facade the way it was designed to

Anything drilled through a facade joint breaks the seal. Ask the installer to reseal it properly with a compatible product.

Tie resealing in with redecoration, cladding repairs or other access. Sharing the access keeps the cost down and limits disruption.

Do you need facade sealing in Egham Hythe?

Overlaying old sealant is a common shortcut that fails quickly. Cured silicone won’t accept a new silicone bead, so the new bead peels away within a season or two.

Things that usually lead to an enquiry:

  • Perimeter sealant that has split or peeled away
  • Staining on stone next to old sealant
  • Hard, chalky sealant that no longer flexes
  • Damp patches beside frames after rain

Projects at colleges like Strode's College, 1.3 miles north-west of Egham Hythe, tend to run to term dates, so the mastic is planned tightly.

How to choose a sealant contractor

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Egham Hythe can sit alongside others in a wider programme.

Facades, frames and programmes in Egham Hythe

Egham Hythe is about 19 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme. Egham Hythe is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager.

For contractors refurbishing units at places like Pine Trees Business Park, which lies north-east of Egham Hythe, the mastic covers cladding panels, roller-door and window perimeters. Hospital estates such as Ashford Hospital (to the north-east of Egham Hythe) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

Our process

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes a day or two for a few elevations, and longer where access has to be moved around the building, and we clear our waste as we work. What matters most for a job in Egham Hythe is a clear list of what needs doing, so send photos of each area. You’ll then get a fixed price for the work.

  1. We start with photographs, drawings or a visit to see the joints and agree access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out in full and the joint faces cleaned.
  4. Primer goes on where the product data asks for it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

What we need from you

  • Make sure the joints can be reached
  • Send asbestos survey details if the building is pre-2000
  • Tell staff and tenants when we will be in

Questions about Egham Hythe

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

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Could you schedule work at a campus like Royal Holloway University for the vacation?

Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

When is resealing likely to be due?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Will you check whether the sealant is causing the leak?

Yes. Photos help, and you can call the office on 01277 525 020 or send photos by email to arrange a visit. Failed perimeter sealant is a common cause, but not the only one, and we’ll tell you which.

How is access to upper-level joints handled?

That varies with the building and the access on offer. When you call the office on 01277 525 020 or email us, describe the access.

Can one quote cover more than one building?

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