Need facade sealing in Wexham Street?

Facade sealing in Wexham Street, done properly

We are often asked to look at water coming in around frames. Very often the perimeter bead has cracked or lost its grip, though that isn’t the only cause. We will tell you if we think the leak is coming from somewhere sealant won’t fix. The enquiries we see most involve old perimeter mastic that has dried out and draughts around frames and panels, on coping and flashing joints, stone and brick facade joints and cladding panel joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Wexham Street is the same: the right product in a properly prepared joint.

Construction in and around smaller places such as Wexham Street is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Common questions from Wexham Street clients

Could you schedule work at a campus like Buckinghamshire New University for the vacation?

Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Can you work at a site such as The Business Village, by Wexham Street?

Yes. Estates, retail parks and business parks around Wexham Street, The Business Village among them, are all within reach. Photos and a short description are enough for a first look.

Can staff carry on working while you are here?

Normally, yes. We phase the work so most of the building stays in use, with each area protected and signed.

How long does a job like this take?

That varies with the scale of the job, though a typical visit typically takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. Larger or phased jobs take longer, and we will give you a timescale with the quote.

What hours do you work?

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

Is the work guaranteed?

Yes. Workmanship is guaranteed for 12 months.

Can one quote cover more than one building?

Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.

Different surfaces, different methods

Brick and stone facades

On masonry, the sealant has to suit a porous, textured surface. Neutral-cure products are used because acetoxy types can mark some stone, and primers go on where specified.

Perimeter joints at frames and structure

The joint around a framed system, where it meets the structure, needs sealant. We seal those perimeter joints rather than the system it surrounds.

New build and refits around Wexham Street

A 2-mile radius around Wexham Street takes in several hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. Wexham Street is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team.

For a contractor at a hotel such as The Pinewood Hotel, 1.4 miles to the south-east of Wexham Street, the mastic often has to be finished before a reopening date. On a healthcare site such as Spire Thames Valley Hospital (less than half a mile south-east of Wexham Street), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Wexham Street is about 2 miles north-east of Slough, in Buckinghamshire. We cover Wexham Street, with the same fixed quotes and 12-month guarantee as everywhere else. Wexham Street is one of 308 places in Buckinghamshire on our list for facade joints. Reading is covered too, some 19 miles away.

What affects the price in Wexham Street

To price the job, we consider:

  • Access and working height
  • Working within restricted access windows
  • Site requirements such as inductions and permits
  • Quantities, in metres or numbers

Pricing facade joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

Details that help us quote

Whether it’s one area or a whole building, these details speed things up:

  • A wide shot and a close-up of the area
  • The product your specification calls for
  • Rough lengths or quantities, or drawings if you have them
  • Whether the building will be occupied during the work

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, speak to us on 01277 525 020 or send details through our quote form.

When to call us in Wexham Street

When sealant lets go of a frame or panel, the cause is often the preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond.

Look out for the following:

  • Cladding panel joints that have opened up
  • Previous reseals run over old sealant
  • Water coming in around window frames
  • Weathered joints at frame-to-structure perimeters

For contractors on a campus like Buckinghamshire New University (3.9 miles east of Wexham Street), facade and perimeter sealing has to fit around students and term dates.

Before you book anyone

  • Do they follow the manufacturer’s priming guidance?
  • Will CSCS-carded applicators be on site?
  • What level of public liability insurance do they hold?
  • The terms of the workmanship guarantee

Choosing a commercial sealant contractor

Honest limits

Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:

  • Joints whose design needs changing by the specifier
  • Render or concrete edges that have broken away
  • Water getting in through cracked render or porous masonry

If in doubt, ring 01277 525 020 or email a schedule or drawings and we will say what we think.
