Facade sealing for businesses in Hatton

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Our process

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Planning a London job such as one in Hatton starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out 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. We go over the completed work with you before leaving.

Preparing the site

  • Flag any permit to work we’ll need
  • Share your working hours and any access restrictions
  • Point out parking and an unloading spot

About our facade sealing in Hatton

Sealant around windows, doors and cladding panels stops rain reaching the wall behind. Once a perimeter seal fails, water tracks in around frames and panels. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. The enquiries we see most involve previous reseals run over old sealant and water coming in around window frames, across cladding panel joints, stone and brick facade joints and window and door perimeters. Most enquiries from Hatton start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

Around Hatton, as across London, much of the work is refurbishing existing buildings as well as building new ones. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by, so tidy, well-planned work matters.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Surface by surface

Perimeter joints at frames and structure

The joint around a framed system, where it meets the structure, needs sealant. We seal those perimeter joints, not the framing or glazing itself.

Render and coated surfaces

Where the joint will be painted over, a paintable hybrid or PU sealant may suit. The choice depends on the specification and finish.

What happens if it’s left?

A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Leaks travel along the structure, so the real damage is often some distance away. In Hatton, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Building and refurbishing in Hatton

The area within 2 miles of Hatton holds a good number of hotels. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight. Site traffic in Hatton falls within London’s ULEZ, like everywhere else in Greater London. Add booked deliveries and tight storage, and the mastic package needs planning with the site team.

New wings at hospitals like Ashford Hospital (2.7 miles south-west of Hatton) bring long runs of window and panel joints to seal. University estates such as University of London, 3.7 miles to the east of Hatton, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. When a college such as West Thames College - Skills Centre (to the south-east of Hatton) builds or refurbishes, the mastic package normally has to fit around students and staff.

When something else is needed

Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:

  • Arranging specialist high-level access, which is planned with the client
  • Damaged frames that need replacing
  • Leaks from roofs, gutters or failed flashings rather than sealant joints

Not sure which it is? You can speak to us on 01277 525 020 or email us and we will tell you honestly.

Joints and surfaces we work on

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

FAQs: Hatton

Will you plan work around the academic year at somewhere like University of London?

Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Can you work at a site such as Eastern Business Park, by Hatton?

Yes, sites like Eastern Business Park are within our area, along with the rest of Hatton. To start, just call 01277 525 020 or email the details over with the unit, the joints involved and your access times.

Can you find out why a window is leaking?

Yes. We check the sealant joints and report what we find before quoting. If the water seems to come from a roof, sill or the glazing unit instead, we say so.

What do you charge?

Every job gets its own fixed quote. To get one, give us a call on 01277 525 020 or email drawings and photos with a description of the work.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Do we need an asbestos check before resealing?

In older non-domestic buildings, old sealant can contain asbestos. The dutyholder’s asbestos register should be checked first. We don’t remove asbestos-containing materials.

Which sealant will you use?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

After the work

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

  • Check that rainwater leaves the facade the way it was designed to
  • Avoid patch repairs on failed facade joints
  • Plan facade sealing alongside redecoration
  • Don’t wait for a second leak before calling

Hold back any cleaning crew until the joints have had their stated cure time. Keep high-pressure jets and strong chemicals away from new sealant, so brief your window cleaners.

Use each reseal to correct the joint: the right width, backing rod and a sealant with enough movement capability. A well-designed joint lasts longer than a like-for-like copy of a failed one.

Should maintenance staff do it?

Putting right a botched joint often costs more than sealing it well at the start, 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.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
