About our facade sealing in Newbury

A good facade joint depends on design as much as product. 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. If you are dealing with damp patches beside frames after rain and perimeter sealant that has split or peeled away, we can help. A specialist sealant contractor works differently from a general builder: in Newbury, that means joint design, primers and backing rod as standard.

In towns like Newbury, sites are typically modest: small housing schemes, extensions to schools and surgeries, refurbished shops and offices. A mastic package on a smaller site still needs the same care at window perimeters and facade joints.

Work we carry out in West Berkshire comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or email the details over and we’ll come back to it.

Facades, frames and programmes in Newbury

Newbury is about 53 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes. There are a good number of hotels within about 2 miles of Newbury. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight.

School extensions, at buildings such as St Nicolas C.E. Junior School, typically run to the summer holidays, mastic included. When units on a site such as Parkway Shopping Centre (under half a mile north of Newbury) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Newbury is about 15 miles west of Reading, in West Berkshire. Any commercial site in Newbury is covered, whether it’s a single job or part of a planned programme. Our West Berkshire coverage takes in 140 places, from busy centres to rural villages. There’s a separate page for Reading, about 15 miles away.

If you need facade sealing in RG14, RG19, RG18 and RG20, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. Buildings on Market Street, London Road and Donnington Square are within our area for facade joints. Being close to the A4 and A339, Newbury is straightforward for us to reach. We also cover Greenham (1 mile south-east), Sandleford (1 mile south), Skinners Green (2 miles south-west), Wash Common (2 miles south-west) and Enborne (2 miles west) for facade joints. Nearby towns on our patch include Thatcham (3 miles east), Burghfield Common (11 miles east), Hungerford (8 miles west), Fords Farm (13 miles east), Little Heath (12 miles east) and Calcot (12 miles east). As one of the bigger centres in West Berkshire, Newbury has a broad mix of commercial, public and industrial buildings, and we cover them all.

What’s near Newbury

Maintenance after handover

Regular inspection catches problems early. In particular:

  • Insist on a full cut-out when joints are renewed
  • Check the asbestos register before old mastic is disturbed
  • Investigate damp beside windows promptly
  • Brief window cleaners about newly sealed joints

Record the sealant type and date on the building file. Future work can then match the product and colour.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos.

Diagnose, treat, sign off

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before the next one starts. For a town like Newbury, we try to group jobs for the same client into one visit, with one quote covering them. Give us your access times and we’ll fit the work in.

  1. Access, site rules and timing are settled with the client up front.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. We remove the old bead and check the edges are sound.
  4. Faces are cleaned, primed where needed and backed.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. Once signed off, the work carries our 12-month guarantee.

Advice

How the job changes by surface

Brick and stone facades

Stone can absorb plasticisers from the wrong sealant. The specified stone-compatible sealant is what we use, and mask the edges carefully.

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.

What we are called out for in Newbury

Not every failure is in the sealant: if the edge of the render, concrete or coating breaks away, the bead goes with it. We tell you when the edges need repairing before resealing.

Clients typically get in touch after noticing one or more of the following:

  • Weathered facade joints that have lost their grip
  • New sealant peeling off old mastic
  • Failed seals around shopfront and entrance frames
  • Leaks at window and door perimeters

For a contractor at a hotel such as Chequer's Hotel, which lies north of Newbury, the mastic often has to be finished before a reopening date.

Before you book anyone

  • The named product and why it was chosen
  • Whether old or failed sealant will be cut out, not overlaid
  • Health and safety accreditation such as CHAS
  • How they handle RAMS and site documents

Choosing a commercial sealant contractor

Doing it in-house

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

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Honest limits

We check first that sealant really is the fix. It won’t put right:

  • Specialist high-level access methods
  • Joints too narrow for the movement they take, which need redesign
  • Replacing glass or failed glazing units

If you’re not sure, just give us a call on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.

Joints and surfaces we work on

  • Perimeter joints where frames meet the structure

Your questions answered

Could you schedule work at a campus like Newbury College 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.

Do you cover business parks and estates near Newbury, such as Parkway Shopping Centre?

Yes. Our area takes in Newbury and its surroundings, with estates and business parks such as Parkway Shopping Centre included. Photos and a short description are enough for a first look.

Do you work in Newbury?

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

Who decides which product is used?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Can you handle several sites?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

Do you offer coloured sealant?

That depends on the product. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.

Can you work on upper floors?

That varies with the building and the access on offer. When you phone 01277 525 020 or email the details over, describe the access.
