Facade sealing in Winkfield Street

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 with the ratio the sealant maker recommends, often around 2:1. We work on stone and brick facade joints, window and door perimeters and perimeter joints where frames meet the structure, and the usual reasons a site gets in touch are staining on stone next to old sealant and failed seals around shopfront and entrance frames. Looking for mastic applicators who cover Winkfield Street? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

Sites around smaller places like Winkfield Street can be a fair drive from suppliers, so we come with everything the package needs. Drawings, photographs 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.

Questions about Winkfield Street

Can work at a site such as Imperial College Silwood Park Campus fit around teaching?

Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Do you take on work at healthcare sites like Heatherwood Hospital?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Do you replace failed glazing units?

No. We don’t install glazing systems, windows or glass. We seal the joints around them, including perimeters where frames meet the structure.

Do you cover Winkfield Street?

Yes. Sites across Winkfield Street are covered, with one number for every area we cover.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Can you find out why a window is leaking?

Yes. We look at the perimeter sealant and tell you whether it has failed before quoting. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.

What’s the quickest route to a quote?

You can use the quote form on this site; alternatively, call 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.

Diagnose, treat, sign off

Tell us your site hours and access windows and we will plan around them. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Jobs in and around smaller places like Winkfield Street are typically planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. Failed sealant is cut out along its full length.
  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. The completed runs are checked with you, then the 12-month guarantee applies.

Why act early in Winkfield Street

Open facade joints also let air and dirt through: draughts around frames add to heating costs and complaints. Resealing deals with the draught as well as the leak. Older rural buildings around Winkfield Street move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Pricing facade joints depends on quantities, condition and access. Call for a quote.

When something else is needed

Being straight saves everyone time. New sealant won’t cure:

  • Movement beyond what any sealant can handle
  • Cracked or spalling substrates that need repair before sealing
  • Work on the window or framing system itself

Not sure which it is? You can phone 01277 525 020 or email us and we’ll tell you honestly.

Joints and surfaces we work on

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

Building and refurbishing in Winkfield Street

Winkfield Street sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team. Winkfield Street lies roughly 27 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes.

Hospital estates such as Heatherwood Hospital (to the south of Winkfield Street) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. On a campus such as Imperial College Silwood Park Campus, 3.6 miles south-east of Winkfield Street, new teaching buildings and residences are usually built and refurbished around the academic year.

Winkfield Street is about 3 miles north-east of Bracknell, in Bracknell Forest.

When to call us in Winkfield Street

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:

  • Unsightly perimeter sealant on a visible elevation
  • Leaks at window and door perimeters
  • Old perimeter mastic that has dried out
  • Weathered joints at frame-to-structure perimeters

For a contractor at a hotel such as Stirrups Country Hotel, under half a mile south-west of Winkfield Street, the mastic often has to be finished before a reopening date.

What to look for in a quote

  • How long is the guarantee, and what does it include?
  • Will CSCS-carded applicators be on site?
  • Whether primer will be used where the manufacturer specifies it
  • What level of public liability insurance do they hold?

Choosing a commercial sealant contractor

General trades versus a specialist

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. That’s why many clients bring in a specialist from the beginning.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
