About our facade sealing in West Preston

We seal window and door perimeters, cladding panel joints, external facade joints and perimeter joints where frames meet the structure for clients around West Preston. Coping and flashing joints are included where sealant is the specified fix. We work on shopfront frames, perimeter joints where frames meet the structure and stone and brick facade joints, and what we are called in for most is perimeter sealant that has split or peeled away and damp patches beside frames after rain. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in West Preston, preparation and product choice get the time they need.

Building work in places the size of West Preston is usually small-scale: a handful of new houses, barn conversions, a school or hall extension. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

How a job runs

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. For a job in West Preston, the main thing is a clear picture of the work, so send photographs of each area. You’ll then get a fixed price for the work.

  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 the joint faces cleaned.
  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.

What we need from you

  • Let building users know which areas are affected
  • Explain the parking and delivery arrangements
  • Make sure the joints can be reached

West Preston: questions and answers

Is West Preston too small for you to travel to?

Not at all. West Preston 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.

Is hospital work, at somewhere like Zachary Merton Hospital, something you do?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Which sealant do you use on facades?

It depends on the joint, the substrate and any specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, tell us and we will confirm them with the quote.

Is old mastic on our building likely to contain asbestos?

For older buildings, yes, check before work starts. The duty to manage asbestos sits with the dutyholder. If asbestos is suspected, work stops until it is tested.

Are you insured?

Yes. Our insurance certificate can be sent alongside the quote.

Why it’s worth doing now in West Preston

Leaving failed perimeter sealant also makes the eventual job bigger: edges get wet, render and timber deteriorate and frames can move. Early action keeps it simple. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

What you get with us

Surface by surface

Precast concrete panels

Precast panel joints have to absorb thermal and structural movement. A sealant of the right movement class goes in over backing rod, primed where the maker specifies.

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.

After the work

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

  • Check the asbestos register before old mastic is disturbed
  • Keep pressure washers away from fresh sealant
  • Keep sills, gutters and drainage paths clear
  • Don’t wait for a second leak before calling

Keep gutters, sills and drainage paths clear. Sealant copes better when water runs off the facade as designed instead of soaking the joints.

Coordinate facade sealing with other external works. Sharing the access keeps the cost down.

Cost factors for facade joints

Before we quote, we look at:

  • Location, for remote and island sites
  • Induction, permit and paperwork requirements
  • Removal of failed or old sealant
  • The size and state of each joint

Pricing facade joints depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

Details that help us quote

However big the job, these details speed things up:

  • Asbestos survey details if the building is older
  • The product your specification calls for
  • Approximate linear metres or a joint schedule
  • What the building is and how it’s used

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.

Contractors’ notes for West Preston

West Preston sits close to the coast, within about 1 mile. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, and the sealant, primer and backing need choosing with that in mind. West Preston sits in one of the drier corners of the country, the South East. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, which is why external dates are agreed with the site manager.

Hotel extensions and refits, at places such as The Seaview Hotel, which lies south-east of West Preston, usually run between busy periods, so the sealing is squeezed into short windows. Projects at schools like Georgian Gardens Community Primary School work to term dates, so mastic is programmed tightly. Older buildings in the area around West Preston, such as Ecclesden Manor, which lies north-east of West Preston, need care when sealed: the product has to suit soft or historic materials.
