About our facade sealing in Watersfield

Sealant around windows, doors and cladding panels stops rain reaching the wall behind. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We remove failed sealant and install a new bead chosen for the joint and how far it moves. The enquiries we see most involve perimeter joints where frames meet the structure and staining on stone next to old sealant, across shopfront frames, stone and brick facade joints and window and door perimeters. A specialist sealant contractor works differently from a general builder: on jobs in Watersfield, preparation and product choice get the time they need.

Around smaller places like Watersfield, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

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

FAQs: Watersfield

Do you take on work at healthcare sites like Arundel and District Hospital?

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

Do you cover business parks and estates near Watersfield, such as Quell Farm Industrial Estate?

Yes, sites like Quell Farm Industrial Estate are within our area, along with the rest of Watersfield. Send details of the unit and the work through our quote form for a quick quote.

Can you send site paperwork?

Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.

Is it fine to apply new sealant on top of old?

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

Is colour matching possible?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.

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 email a schedule or drawings, describe the access, and we’ll agree the approach together.

Should we check old sealant for asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Check the asbestos register or survey before it is disturbed; if it’s suspected, work stops until it has been tested. Removal of asbestos isn’t something we do.

Different surfaces, different methods

Brick and stone facades

Brick and stone facades have perimeter and movement joints that need a compatible sealant. Neutral-cure products are used because acetoxy types can mark some stone.

Coping and flashing joints

Not every coping or flashing leak is a sealant problem. We tell you if the fix is a roofing or metalwork job rather than a reseal.

Our process

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, with the work itself typically taking longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. For work around Watersfield, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. We look at the joints, the drawings and the access before pricing.
  2. The old bead is cut away completely, not overlaid.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

Before we start on site

  • Tell us which areas need to stay in use
  • Tell us what induction or permit system the site runs
  • Confirm the product named in the specification

Contractors’ notes for Watersfield

At about 44 miles from central London, Watersfield is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes. Rainfall across the South East, Watersfield included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team.

On a healthcare site such as Arundel and District Hospital, which lies south of Watersfield, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Units on estates such as Quell Farm Industrial Estate (1.1 miles east of Watersfield) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Honest limits

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Water getting in through cracked render or porous masonry
  • Movement beyond what any sealant can handle
  • Installing or repairing glazing systems

If you are not sure, just phone 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.

What we seal

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

General trades versus a specialist

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

Do you need facade sealing in Watersfield?

Sun, rain and temperature swings wear facade sealant down over the years. The bead hardens, chalks on the surface and loses the flexibility to follow the joint.

Look out for the following:

  • Failed sealant on precast panel joints
  • Cold air coming in at window perimeters
  • Facade joints cracked through the middle
  • Patch repairs that keep failing

With historic properties like Bignor Roman Villa (1.8 miles west of Watersfield) in the area, refurbishment work often meets old masonry that needs compatible sealants.

Before you book anyone

  • Their plan for phasing and protecting the area
  • Whether their applicators hold CSCS cards
  • What level of public liability insurance do they hold?
