Facade sealing in Cambridge Heath

We don’t install glazing systems or replace glass. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters, using sealants classified for facade or glazing use. Most enquiries involve leaks at window and door perimeters and air leaks through failed facade joints, across perimeter joints where frames meet the structure, cladding panel joints and shopfront frames. One point of contact handles commercial sealant work in Cambridge Heath from the first photographs to the final walk-round, whether it’s one building or several.

A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by, so tidy, well-planned work matters.

Work we carry out in Greater London comes with a 12-month guarantee. Should something we installed fail, give us a call on 01277 525 020 or use the quote form and we will come back to it.

What happens if it’s left?

Patch repairs over old sealant tend to come back. A full cut-out and reseal costs more on the day but lasts much longer, so you aren’t paying for the same joint twice. Failed sealant in a building in Cambridge Heath can quickly affect neighbours, tenants or the floor below. Dealing with it early is simpler for everyone.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.

Why appoint us

  • Colour options checked against the specified product
  • Failed material removed, not covered up
  • Sealing commercial buildings since 2005
  • 12 months’ guarantee on every job

Quoting for work in Cambridge Heath

Your fixed quote is built from the real scope. It takes account of:

  • The total length or number of joints
  • Specialist products, such as fire-rated or hygienic sealants
  • Induction, permit and paperwork requirements
  • Removal of failed or old sealant

Pricing facade joints depends on how many there are, their condition and the access, plus any specification you’re working to. Ask us for a fixed quote.

Sending details for a quote

We can often quote from photos and a few details. Please tell us:

  • What the building is and how it’s used
  • Clear photos of the problem areas
  • How the joints are reached, and at what height
  • The postcode of the building

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.

Our process

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact. All of Greater London is in the ULEZ, and kerbside space in Cambridge Heath can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.

  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. Failed beads are removed in full and the joint faces cleaned.
  4. Primer is applied where the maker specifies it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. We go over the completed work with you before leaving.

Getting the site ready

  • Have the specification and drawings to hand
  • For older buildings, check the asbestos register before work
  • Tell us your opening times and when work is allowed

When it isn’t the sealant

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be one of these:

  • Joints too narrow for the movement they take, which need redesign
  • Arranging specialist high-level access, which is planned with the client
  • Work on the window or framing system itself

If in doubt, speak to us on 01277 525 020 or send photos by email and we will say what we think.

Joints and surfaces we work on

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

Facade sealing in Cambridge Heath: the local picture

The ULEZ covers the whole of Greater London, Cambridge Heath included, so site vehicles need to meet its standards or pay the daily charge. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for. Cambridge Heath has a good number of hotels close by, all within 2 miles. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included.

Units on estates such as Bayford Street Industrial Centre (to the north of Cambridge Heath) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. When a college such as CECOS College London (1 mile south-east of Cambridge Heath) builds or refurbishes, the mastic package typically has to fit around students and staff. Building work at universities like Queen Mary University of London, 0.9 miles south-east of Cambridge Heath, is often timed for the summer, mastic included.

Cambridge Heath is about 1 mile north-east of Shoreditch, in Greater London. Commercial clients in Cambridge Heath can call on us for facade joints, as part of our coverage of Greater London. Cambridge Heath is one of 764 places in Greater London on our list for facade joints.

How the job changes by surface

Coping and flashing joints

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

Brick and stone facades

Brick and stone facades have perimeter and movement joints that need a compatible sealant. Neutral-cure products are used because acetoxy types can mark some stone.

Aftercare for building managers

A few simple habits keep the new joints working:

  • Keep sills, gutters and drainage paths clear
  • Confirm the survey covers external sealants in older buildings
  • Avoid harsh cleaners on facade sealant
  • Combine resealing with other works that need access

Look at perimeter and panel joints as part of routine building checks. Signs to look for are cracking, edges lifting, chalking and stiffness; note where they appear.

Use each reseal to correct the joint: correct depth, proper backing and a sealant that can take the movement. Repeating a faulty detail just repeats the failure.

Questions we are asked in Cambridge Heath

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

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Can you work in a London building with booked loading and goods-lift slots?

Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it

How long does a job like this take?

That varies with the scale of the job, but the work typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather. For bigger or phased jobs, we’ll set out a timescale with the quote.

What type of sealant goes on window perimeters?

Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Some joints call for hybrid, PU or polysulphide instead, as the specification or substrate requires.

Can you work on upper floors?

Access is planned with you before we quote. Tell us about access: existing scaffold, what you are arranging and any site restrictions, and we’ll price the work around it.

Do you offer coloured sealant?

That depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

Can you work to our specification?

Yes. Send it with your enquiry, and the quote will be based on it.
