Facade sealing in Mayford, done properly

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 remove failed sealant and install a new bead chosen for the joint and how far it moves. If you have cladding panel joints that have opened up and new sealant peeling off old mastic, we can put it right, whatever the surface. Facilities teams, main contractors and managing agents in Mayford tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Sites around smaller places like Mayford can be a fair drive from suppliers, so we come with everything the package needs. Drawings, photos and the programme let us give a fixed quote.

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

Diagnose, treat, sign off

Before we leave any area, we remove the tape, clean down and inspect every joint, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. If others near Mayford need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  1. We look at the joints, the drawings and the access before pricing.
  2. The old bead is cut away completely, not overlaid.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. We walk the finished joints with you before handing over.

Preparing the site

Advice

Questions we’re asked in Mayford

Is hospital work, at somewhere like Woking Community Hospital, something you do?

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

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

Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

When can you be on site?

The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.

Which sealant do you use on facades?

Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others.

Is old mastic on our building likely to contain asbestos?

In older non-domestic buildings, old sealant can contain asbestos. The dutyholder’s asbestos register should be checked first, and if anything is suspected, we stop until it’s tested. We don’t remove asbestos-containing materials.

Do you cover Mayford?

Yes. We cover Mayford, and you can call the office on 01277 525 020 or email us to get started.

Is it fine to apply new sealant on top of old?

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

Common problems we fix in Mayford

Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. The joint may be too narrow, the bead too thin or the sealant the wrong movement class.

Typical triggers for a call:

  • Discoloured or dirty facade joints
  • Water coming in around window frames
  • Perimeter joints where frames meet the structure
  • Hard, chalky sealant that no longer flexes

Building work at universities like University of Surrey (3.6 miles south-west of Mayford) is often timed for the summer, mastic included.

Questions to ask before you book

  • How long is the guarantee, and what does it include?
  • Will CSCS-carded applicators be on site?
  • Do they follow the manufacturer’s priming guidance?
  • How they handle RAMS and site documents

Questions to ask before you appoint anyone

Maintenance after handover

Problems stay small when the joints are checked regularly. In particular:

  • Inspect facade joints on a regular cycle
  • Record the product and colour used on each elevation
  • Share access with other external trades
  • Check the asbestos register before old mastic is disturbed

Let the new sealant cure before washing the facade or windows near it. Keep high-pressure jets and strong chemicals away from new sealant and tell your cleaning contractor.

Check older buildings for asbestos before disturbing old mastic. Older sealants can contain asbestos, and if it’s suspected, we stop until it has been tested.

Site staff or a sealant specialist?

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Facade sealing in Mayford: the local picture

Mayford 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 the external programme keeps a little slack. At about 25 miles from central London, Mayford is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme.

New wings at hospitals like Woking Community Hospital (1.4 miles north of Mayford) bring long runs of window and panel joints to seal. Projects at colleges like Woking College (1.2 miles north-east of Mayford) tend to run to term dates, so the mastic is planned tightly.

How the quote is worked out

A fixed quote reflects the actual work. It takes account of:

  • Distance, for remote addresses
  • Whether old sealant has to be cut out first
  • Backing rod, priming and other preparation
  • The product specified

The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.

What to include in your enquiry

There’s no need for a formal survey. These details are enough to start:

  • Where the site is, with the postcode
  • Specification clauses that apply
  • What the building is and how it’s used
  • Your programme or deadline

Pricing a project or setting a maintenance budget? We will quote against your scope and drawings that you can work with. For a chat about it beforehand, call 01277 525 020 or send details through our quote form.

Owners, agents and contractors

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, and our applicators hold CSCS cards.

We work for building owners and managing agents on everything from one building to a spread of sites. Several sites can go on one quote, which keeps the paperwork simple.
