Facade sealing across Chidham

Facade sealing in Chidham, done properly

Every facade quote starts with how the joints will be reached. Let us know what access exists or is planned, and any site rules we need to work around, and we will fit the work around it. Site teams most often ask us about weathered facade joints that have lost their grip and unsightly perimeter sealant on a visible elevation, across window and door perimeters, perimeter joints where frames meet the structure and shopfront frames. Facilities teams, main contractors and managing agents in Chidham tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

In the countryside around places like Chidham, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Diagnose, treat, sign off

Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, we take the joints in the sequence agreed with you. If others near Chidham need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  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.
  4. Primer is applied where the maker specifies it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. We go over the completed work with you before leaving.

Before we start on site

  • Tell us which areas need to stay in use
  • Clear stock, furniture or equipment away from the joints
  • Send asbestos survey details if the building is pre-2000

Ask for a quote

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.

Advice

Your questions answered

Is a smaller place like Chidham outside your area?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Could you schedule work at a campus like University of Chichester for the vacation?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll 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.

What hours do you work?

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

How do we ask for a quote?

The quote form is the simplest route, though you can also call 01277 525 020 or email us. Include photos or drawings if you have them.

Do you seal on top of existing sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Can you work on upper floors?

That varies with the building and the access on offer. When you speak to us on 01277 525 020 or use the quote form, describe the access, and we’ll plan the work with you.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Honest limits

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:

  • Arranging specialist high-level access, which is planned with the client
  • Water getting in through cracked render or porous masonry
  • Installing or repairing glazing systems

If in doubt, speak to us on 01277 525 020 or email the details over and we will say what we think.

Joints and surfaces we work on

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

Doing it in-house

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Building owners, agents and FMs in Chidham

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Aftercare for building managers

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

  • Ask about asbestos in pre-2000 mastic
  • Never let anyone seal over old sealant
  • Check that rainwater leaves the facade the way it was designed to
  • Brief window cleaners about newly sealed joints

After heavy weather, check vulnerable elevations for signs of water inside. An early report typically means a small reseal rather than a bigger repair.

Don’t wait for a full elevation to fail. Small repairs stop small leaks becoming large ones inside the building.

When to call us in Chidham

Three-sided adhesion is a classic installation fault. With no backing, the sealant is restrained and tears as the joint moves.

If one of these sounds familiar, it’s time for a closer look:

  • Facade joints cracked through the middle
  • Cold air coming in at window perimeters
  • Old perimeter mastic that has dried out
  • Failed seals around shopfront and entrance frames

When a school such as Chidham Parochial Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

Comparing quotes

  • Can the work be phased to keep areas open?
  • Health and safety accreditation such as CHAS
  • Do they follow the manufacturer’s priming guidance?
  • Who will actually carry out the work

How to choose a sealant contractor

Sites and facades in and around Chidham

Chidham sits close to the coast, within about 1 mile. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, and the sealant, primer and backing need choosing with that in mind. 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.

Building work at universities like University of Chichester, 4.5 miles to the east of Chidham, is often timed for the summer, mastic included. Hotel extensions and refits, at places such as Millstream Hotel, 0.8 miles to the east of Chidham, usually run between busy periods, so the sealing is squeezed into short windows.

Chidham is about 4 miles west of Chichester, in West Sussex. Commercial clients in Chidham use us for work on facade joints. Chidham is one of 373 places we cover in West Sussex. We also cover Portsmouth, around 9 miles from Chidham.
