Facade sealing across Horsell

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Facade sealing in Horsell

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 with products suited to facade or glazing perimeter joints. If you’re dealing with discoloured or dirty facade joints and sealant pulling away from frames or panels, we can help, on stone and brick facade joints, window and door perimeters and coping and flashing joints alike. A single leaking joint is often how a building in Horsell first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

For a contractor on a smaller site near Horsell, one mastic visit at the right stage saves return trips. Let us know the key stages and we’ll time the work so nothing waits on us.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

General trades versus a specialist

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Keeping the joints sound

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

  • Inspect facade joints on a regular cycle
  • Keep the sealant details on the building file
  • Keep sills, gutters and drainage paths clear
  • Insist on a full cut-out when joints are renewed

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

Planned resealing is cheaper than reacting to leaks. Inspect regularly and reseal sections as they start to fail instead of after the damage.

What happens if it’s left?

Leaving failed perimeter sealant also makes the eventual job bigger: wet edges break down, so repairs may be needed before resealing. Acting at the first sign of splitting keeps the fix simple. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.

The price depends on how many linear metres there are, what has to come out first and the access. Call for a fixed quote when you’re ready.

Building and refurbishing in Horsell

Rainfall across the South East, Horsell included, is lower than in many parts of the UK. 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. Horsell is about 23 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme.

For a contractor working at a hospital such as Nuffield Health Woking Hospital (less than half a mile north of Horsell), perimeter and facade sealing is planned around patients and deliveries. For contractors at a school such as Woking High School, sealing has to be finished before term starts. Hotel extensions and refits, at places such as DoubleTree by Hilton Hotel Woking, 0.5 miles south-east of Horsell, typically run between busy periods, so the sealing is squeezed into short windows.

Horsell is about 1 mile north-east of Woking, in Surrey. We cover Horsell and the rest of Surrey, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Horsell is one of 379 places we cover in Surrey. Reading is covered too, around 20 miles from Horsell.

We take on facade joints across the GU21 and GU22 postcode area. We cover commercial and managed buildings on Elm Road, Heath Road and Popes Lane. Access to Horsell is via the A3046. Sites close to Horsell are covered too, including Woking (1 mile south-west), Goldsworth Park (1 mile south-west), Mimbridge (1 mile north-west), Sheerwater (1 mile east) and St John's (2 miles south-west). Further afield, our area takes in Guildford (6 miles south), Camberley (7 miles west), Epsom (13 miles east), Farnham (13 miles south-west), Ewell (13 miles east) and Egham (7 miles north).

Different surfaces, different methods

Cladding panel joints

Panel joints on cladding and rainscreen systems take movement every day. The sealant has to match the movement and the panel finish.

Render and coated surfaces

Paintable sealants exist for joints that will be coated. We confirm the product with you before starting.

What affects the price in Horsell

Each job is priced on its own details. The main factors are:

  • Whether old sealant has to be cut out first
  • Any access equipment needed
  • How much there is to seal
  • The site’s rules and procedures

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Details that help us quote

For an accurate fixed quote, we need to understand the site. Send us:

  • Drawings or a marked-up plan, if available
  • Access details, including height
  • Whether an asbestos survey exists
  • What the building is and how it’s used

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.

Your questions answered

Can work at a site such as Woking College fit around teaching?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Is Horsell too far out for you?

Not at all. Horsell is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Does the weather affect the work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, let us know and we will send them with the quote.

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’ll arrange a visit before quoting.

Can you fit around our working hours?

We are in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.

On site: what to expect

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then handed back before we move to the next. Work in places the size of Horsell is planned as a single visit where we can. Clear photographs and measurements help us bring the right products.

  1. We look at the joints, the drawings and the access before pricing.
  2. The old bead is cut away completely, not overlaid.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  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.

What we need from you

  • Arrange parking or a loading space
  • Share the asbestos register for older buildings
  • Make sure the joints can be reached
