Facade sealing near Chailey

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Maintenance after handover

Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:

  • Avoid patch repairs on failed facade joints
  • Note when each elevation was last resealed
  • Investigate damp beside windows promptly
  • Keep sills, gutters and drainage paths clear

Hold back any cleaning crew until the joints have had their stated cure time. Pressure washers and harsh cleaners can damage a fresh bead.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it.

Facade sealing in Chailey, done properly

Most facade joint failures trace back to the joint, not just the sealant. The width has to suit the expected movement and the sealant’s movement capability, while rod fixes the depth and stops the bead sticking to the rear, often at around 2:1 width to depth, as the manufacturer advises. The enquiries we see most involve water coming in around window frames and draughts around frames and panels, on cladding panel joints, perimeter joints where frames meet the structure and window and door perimeters. One point of contact handles commercial sealant work in Chailey from the first photos to the final walk-round, for single jobs and planned programmes alike.

Sites around smaller places like Chailey 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.

Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

What we are called out for in Chailey

Sometimes the substrate is the problem: crumbling render, spalling concrete or flaking paint take the sealant with them. We tell you when the edges need repairing before resealing.

Most enquiries start with one or more of the following:

  • Unsightly perimeter sealant on a visible elevation
  • Weathered facade joints that have lost their grip
  • Gaps between rainscreen or cladding panels
  • Previous reseals run over old sealant

Extensions at sites like Princess Royal Hospital, 4.1 miles north-west of Chailey, normally sit beside working departments, and the mastic follows strict access rules.

Questions to ask before you book

  • Their pre-qualification and accreditations
  • The terms of the workmanship guarantee
  • Will RAMS and insurance details be available?
  • Do they follow the manufacturer’s priming guidance?

Choosing a commercial sealant contractor

How the quote is worked out

Quotes vary with the job. It mainly depends on:

  • The site’s rules and procedures
  • Backing rod, priming and other preparation
  • Whether old sealant has to be cut out first
  • Whether the work must be split into stages

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

Details that help us quote

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • Your programme or deadline
  • A wide shot and a close-up of the area
  • Whether the building will be occupied during the work
  • The site address and postcode

The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or phone 01277 525 020 or send details through our quote form if you’d rather talk the job through.

Questions about Chailey

Is a smaller place like Chailey outside your area?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Can you take on a job at a hospital such as Princess Royal Hospital?

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.

Do you replace failed glazing units?

No. A glazing contractor handles that. What we seal are the joints around frames and panels on commercial buildings.

Can you quote from photographs?

That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.

How long does a job like this take?

The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.

What type of sealant goes on window perimeters?

The product follows the joint’s movement, the surfaces and the specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them and we follow the specified product.

How long do sealant joints last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Sites and facades in and around Chailey

The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager. Chailey is about 37 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 contractors on a campus like University of Sussex, 1.2 miles west of Chailey, facade and perimeter sealing has to fit around students and term dates. For contractors at a school such as Chailey St Peter's Church of England Primary School, sealing has to be finished before term starts.

Doing it in-house

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

What we can’t put right

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:

  • Render or concrete edges that have broken away
  • Replacing glass or failed glazing units
  • Arranging specialist high-level access, which is planned with the client

Not sure which it is? You can call the office on 01277 525 020 or send details through our quote form and we’ll tell you honestly.

Surfaces we seal

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

From enquiry to sign-off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. For work around Chailey, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  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. Failed beads are removed in full.
  4. Primer is applied where the maker specifies it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

Getting the site ready

  • Arrange parking or a loading space
  • Send any specification or drawings in advance
  • Move anything stored against the joints
