Facade sealing for Lampton sites

How we handle facade sealing in Lampton

Access is part of every facade job, and we plan it with you before quoting. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site, and we will fit the work around it. We work on cladding panel joints, stone and brick facade joints and coping and flashing joints, and the failures we are asked to look at most are weathered facade joints that have lost their grip and perimeter joints where frames meet the structure. Most enquiries from Lampton start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

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.

Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

After the work

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Investigate damp beside windows promptly
  • Note when each elevation was last resealed
  • Keep pressure washers away from fresh sealant
  • Check that rainwater leaves the facade the way it was designed to

Following storms, look inside for damp or staining near frames. An early report usually means a small reseal rather than a bigger repair.

Planned resealing is cheaper than reacting to leaks. Inspect regularly and reseal sections as they start to fail.

What sets the cost

A fixed quote reflects the actual work. It allows for:

  • Phasing around occupants
  • Backing rod, priming and other preparation
  • How much there is to seal
  • Induction, permit and paperwork requirements

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

Details that help us quote

There’s no need for a formal survey. A few details are enough to get going:

  • The postcode of the building
  • Photos of the joints, close up and from further back
  • What the building is and how it’s used
  • Anything awkward about access or site hours

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, give us a call on 01277 525 020 or send details through our quote form.

From enquiry to sign-off

Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. All of Greater London is in the ULEZ, and kerbside space in Lampton can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. Product choice follows the joint’s movement and substrate.
  3. Failed beads are removed in full and both faces cleaned back.
  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.

Before we start on site

  • Arrange parking or a loading space
  • Share the asbestos register for older buildings
  • Tell us your opening times and when work is allowed

Advice

Leave it or put it right?

The longer a failed joint is left, the more the substrate suffers: edges get wet, render and timber deteriorate and frames can move. Early action keeps it simple. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.

What you get with us

  • Work carried out by CSCS-carded applicators
  • Specification-led, product-correct work
  • One phone line for London, the South East and Scotland
  • Public liability insurance in place

Do you need facade sealing in Lampton?

When sealant lets go of a frame or panel, the cause is often the preparation. Dust, old sealant residue, damp or a missing primer stop it bonding properly.

Site and facilities staff are often the first to spot these:

  • Staining on stone next to old sealant
  • Air leaks through failed facade joints
  • Cladding panel joints that have opened up
  • Leaks at window and door perimeters

Building work at universities like University of London (1 mile east of Lampton) is often timed for the summer, mastic included.

Questions to ask before you book

  • The terms of the workmanship guarantee
  • Whether primer will be used where the manufacturer specifies it
  • How they’ll work around occupants
  • What level of public liability insurance do they hold?

Questions to ask before you appoint anyone

Your questions answered

Is Ebury Business Centre, near Lampton, within your area?

Yes. Estates, retail parks and business parks around Lampton, Ebury Business Centre among them, are all within reach. To start, just speak to us on 01277 525 020 or email the details over with the unit, the joints involved and your access times.

Can you work on a hospital site such as West Middlesex Hospital?

Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.

Can you work while the building is occupied?

In the majority of cases, yes. We phase the work so most of the building stays in use.

Do you run new sealant over the existing bead?

No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the faces are cleaned before resealing. That is what makes the new joint last.

Will you come and look before quoting?

Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we will arrange a visit.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards, which many sites require.

Can you look at water coming in around a frame?

Yes. Photos are often enough to start, followed by a visit if needed. Failed perimeter sealant is a common cause, but not the only one, and we will be honest about which it is.

What we can’t put right

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

  • Joints whose design needs changing by the specifier
  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Work on the window or framing system itself

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

Joints and surfaces we work on

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

New build and refits around Lampton

The area within 2 miles of Lampton holds a good number of hotels. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight. Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Lampton. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for.

For a contractor at a hotel such as Hounslow Central Hotel (0.6 miles south-west of Lampton), the mastic often has to be finished before a reopening date. When a college such as Great Oaks College (to the north-east of Lampton) builds or refurbishes, the mastic package typically has to fit around students and staff.
