Facade sealing for commercial buildings in Chipstead

Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters. The enquiries we see most involve old perimeter mastic that has dried out and cladding panel joints that have opened up, across coping and flashing joints, stone and brick facade joints and shopfront frames. Facilities teams, main contractors and managing agents in Chipstead tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

For a site near Chipstead, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Drawings, photos and the programme let us give a fixed quote.

A 12-month guarantee applies to all our work. Should something we installed fail, phone 01277 525 020 or email the details over and we will come back to it.

Facade sealing around Chipstead: what changes locally

Chipstead is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team. Chipstead is about 14 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme.

For contractors refurbishing units at places like Ullswater Industrial Estate, which lies north-east of Chipstead, the mastic covers cladding panels, roller-door and window perimeters. On a healthcare site such as Royal Marsden Hospital, which lies north of Chipstead, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Chipstead is about 1 mile south-west of Coulsdon, in Surrey. If you’re looking for facade sealing in Chipstead, we can help. 379 places across Surrey fall within our area, including Chipstead. There’s a separate page for London, roughly 14 miles from Chipstead.

Questions we’re asked in Chipstead

Is Chipstead off your patch?

No. Small places get the same service as large ones. We work across Greater London and the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Is hospital work, at somewhere like Royal Marsden Hospital, something you do?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Do you need to see the site first?

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

Should we check old sealant for asbestos?

For older buildings, yes, check before work starts. The dutyholder holds the asbestos register. If asbestos is suspected, work stops until it is tested.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Is the work guaranteed?

Yes. Workmanship is guaranteed for 12 months.

What do you charge?

Each job is quoted on its own details. For yours, give us a call on 01277 525 020 or email the details over with a description of the work.

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 usually takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and our waste is bagged and taken away as we go. If others near Chipstead need work, visits can be combined. You will have a fixed quote before work starts.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. The old bead is cut away completely, not overlaid.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Preparing the site

  • Agree which areas must stay open
  • Have the specification and drawings to hand
  • Arrange parking or a loading space

Getting a fixed quote

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or phone 01277 525 020 or send photos by email if you’d rather talk the job through.

What the job involves on each 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.

Cladding panel joints

Joints between cladding panels open and close with temperature. We use a product rated for the movement and suited to the panel surface.

When it isn’t the sealant

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

If in doubt, phone 01277 525 020 or email us and we will say what we think.

Where we work in Chipstead

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

What we are called out for in Chipstead

New sealant run over old sealant rarely holds. Fresh silicone won’t stick to cured silicone.

It’s worth sending us details if you spot any of the following:

  • Leaks at window and door perimeters
  • Cold air coming in at window perimeters
  • Failed sealant on precast panel joints
  • Facade joints cracked through the middle

Projects at schools like Chipstead Valley Primary School work to term dates, so mastic is programmed tightly.

What your quote should include

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • How they handle RAMS and site documents
  • Their pre-qualification and accreditations
  • What level of public liability insurance do they hold?

Questions to ask before you appoint anyone

Looking after the joints

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

  • Report water ingress at frames as soon as it shows
  • Confirm the survey covers external sealants in older buildings
  • Record the product and colour used on each elevation
  • Avoid harsh cleaners on facade sealant

Include facade joints in your planned maintenance inspections. Watch for splits, gaps at the edges, hardening and discolouration; record the locations.

Tie resealing in with redecoration, cladding repairs or other access. Sharing the access keeps the cost down and cuts time on site.

What happens if it’s left?

The longer a failed joint is left, the more the substrate suffers: edges get wet, render and timber deteriorate and frames can move. Acting at the first sign of splitting keeps the fix simple. Halls, stores and units around places like Chipstead may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Why us?

  • A range of standard colours, depending on the product
  • Colour agreed before work starts
  • Failed material removed, not covered up
  • Public liability insurance in place
