What sealant work can’t fix

If you’re not sure, just ring 01277 525 020 or email us and we’ll give you a straight answer before you book.

What we seal

  • Shopfront frames
  • Stone and brick facade joints
  • Cladding panel joints

Facade sealing in Upperton

We are often asked to look at water coming in around frames. Failed perimeter sealant is a frequent cause, though that isn’t the only cause. We’ll tell you if we think the leak is coming from somewhere sealant won’t fix. If you have hard, chalky sealant that no longer flexes and water coming in around window frames, we can put it right. Most enquiries from Upperton 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 places like Upperton, a lot of construction is the conversion of older buildings, which leaves joints between old walls and new frames that need a sealant able to take the movement.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

What affects the price in Upperton

Quotes vary with the job. It mainly depends on:

  • The size and state of each joint
  • The product specified
  • Site requirements such as inductions and permits
  • How accessible the joints are

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

What we need to price the job

However big the job, the same details help:

  • Any dates the work must fit around
  • Where the site is, with the postcode
  • Whether an asbestos survey exists
  • A wide shot and a close-up of the area

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

Common problems we fix in Upperton

Three-sided adhesion is a classic installation fault. With no backing, the sealant is restrained and rips when the facade moves.

Site and facilities staff are often the first to spot these:

  • Damp patches beside frames after rain
  • Staining on stone next to old sealant
  • Cold air coming in at window perimeters
  • Cladding panel joints that have opened up

Building work at universities like University of Brighton Eastbourne Campus, 1.4 miles south of Upperton, is often timed for the summer, mastic included.

Choosing a commercial sealant contractor

Facade sealing around Upperton: points for this area

Upperton sits close to the coast, within about 1 mile. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so joint design, primers and product choice deserve extra care. Upperton lies roughly 53 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand.

Work at a hotel such as Savoy Court Hotel, 0.9 miles south-east of Upperton, tends to be programmed around bookings, mastic included. For contractors at a college like East Sussex College Eastbourne, which lies north of Upperton, perimeters and internal sealant are timed for the holidays.

Upperton is about 1 mile south-west of Eastbourne, in East Sussex. Upperton sits inside our coverage and the rest of East Sussex, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Upperton is one of 308 places we cover in East Sussex. Our Brighton page has more on work in that area, about 18 miles away.

How the job changes by surface

Coping and flashing joints

Not every coping or flashing leak is a sealant problem. Where the issue isn’t the sealant, we say so.

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, often a low-modulus silicone or hybrid.

Common questions from Upperton clients

Could you schedule work at a campus like University of Brighton Eastbourne Campus for the vacation?

Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Does a coastal location like Upperton affect which sealant is used?

It can. Coastal exposure works external joints harder than inland weather. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

Do you replace windows or glass?

No. Glazing, windows and glass replacement aren’t part of our work. We seal the joints around them, such as perimeter joints where frames meet the structure.

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.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and we will price the work to it.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day.

Can you quote from photos?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.

Diagnose, treat, sign off

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. What matters most for a job in Upperton is a clear list of what needs doing, so send photos of each area. You’ll then get a fixed price for the work.

  1. Access, site rules and timing are settled with the client up front.

Doing it in-house

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
