Facade sealing for Middleton-on-Sea sites

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

Building and refurbishing in Middleton-on-Sea

The sea is no more than about 1 mile from Middleton-on-Sea. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, and the sealant, primer and backing need choosing with that in mind. Middleton-on-Sea is about 54 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme.

Hotel extensions and refits, at places such as Ancton House Hotel, which lies east of Middleton-on-Sea, typically run between busy periods, so the sealing is squeezed into short windows. School extensions, at buildings such as Bishop Tufnell CofE Primary School, normally run to the summer holidays, mastic included. On a campus such as University of Chichester (Bognor Campus) (2 miles west of Middleton-on-Sea), new teaching buildings and residences are typically built and refurbished around the academic year.

Facade sealing in Middleton-on-Sea, done properly

External joints face UV, rain, temperature swings and building movement all year, so they don’t last indefinitely. Life depends on movement, weathering, product choice and the quality of the original work. When the time comes, we cut the old sealant out completely and start again. Site teams most often ask us about failed sealant on precast panel joints and draughts around frames and panels, on perimeter joints where frames meet the structure, coping and flashing joints and stone and brick facade joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Middleton-on-Sea it comes down to the same thing: the right product in a properly prepared joint.

Around places like Middleton-on-Sea, 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.

Why act early in Middleton-on-Sea

Each spell of rain drives water past a failed facade joint. Behind the frame, that can mean damp plaster, stained ceilings, corroded fixings and damaged insulation. Resealing early costs far less than repairing what the water reaches. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.

A quote for facade joints depends on how many there are, their condition and the access, plus any specification you are working to. Call for a quote.

What the job involves on each surface

Window and door perimeters

Frame-to-wall joints at windows and doors are the facade joints we reseal most. A low-modulus, neutral-cure product suits most frame-to-wall joints finished to throw water off the joint.

Perimeter joints at frames and structure

Perimeter joints at frames often show their age first. They are cut out, cleaned, backed and resealed with a product suited to glazing perimeters.

Middleton-on-Sea: questions and answers

Would you work within a site like Bognor Regis War Memorial Hospital?

Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is Ford Airfield Industrial Estate, near Middleton-on-Sea, within your area?

Yes. Our area takes in Middleton-on-Sea and its surroundings, with estates and business parks such as Ford Airfield Industrial Estate included. To start, just call 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.

Is the work guaranteed?

Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.

Do you install glazing systems?

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

Do you hold CHAS accreditation?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Do you cover Middleton-on-Sea?

Yes. Middleton-on-Sea is in our area and the rest of West Sussex, within our coverage of Greater London, South East England and Scotland. For a quote, phone 01277 525 020 or use the quote form.

Can you quote from photos?

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

Diagnose, treat, sign off

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and we clear our waste as we work. For a job in Middleton-on-Sea, the main thing is a clear picture of the work. A fixed quote follows.

  1. We look at the joints, the drawings and the access before pricing.
  2. Failed sealant is cut out along its full length.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

How the quote is worked out

Your fixed quote is built from the real scope. It takes account of:

  • The product specified
  • The site’s rules and procedures
  • Working within restricted access windows
  • How accessible the joints are

There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

Details that help us quote

There’s no need for a formal survey. A few details are enough to get going:

  • Any specification or named product
  • The postcode of the building
  • A wide shot and a close-up of the area
  • Anything awkward about access or site hours

To get a fixed quote, speak to us on 01277 525 020 or email a schedule or drawings. You can also send details through our quote form.

Aftercare for building managers

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

  • Combine resealing with other works that need access
  • Record the product and colour used on each elevation
  • Clear debris that holds water against joints
  • Never let anyone seal over old sealant

If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Ask the installer to reseal it properly using a matching sealant.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos, and if it’s suspected, we stop until it has been tested.
