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

Questions we’re asked in Lower Earley

Will you plan work around the academic year at somewhere like University of Reading - Whiteknights Campus?

Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Is a smaller place like Lower Earley outside your area?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

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: its movement, its surfaces and what it has to cope with.

Will you check whether the sealant is causing the leak?

Yes. Photos help, and you can call the office on 01277 525 020 or email drawings and photos to arrange a visit. Many frame leaks are sealant failures, though not all.

How do we ask for a quote?

The quote form is the simplest route, though you can also speak to us on 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.

Do you offer coloured sealant?

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

When can the area be used after sealing?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

About our facade sealing in Lower Earley

A good facade joint depends on design as much as product. Joint width needs to match how far the joint moves and how far the sealant can stretch, and closed-cell rod sets the depth, keeping the bond to two faces with the ratio the sealant maker recommends, often around 2:1. We work on stone and brick facade joints, window and door perimeters and cladding panel joints, and what we are called in for most is cold air coming in at window perimeters and leaks at window and door perimeters. Whoever orders the work in Lower Earley, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

Around places like Lower Earley, a lot of construction is the conversion of older buildings, and the sealant at those junctions has to cope with two materials that move differently.

A 12-month guarantee applies to all our work. If an installation problem shows up, speak to us on 01277 525 020 or email us and we will arrange a return visit.

Why deal with it now?

The longer a failed joint is left, the more the substrate suffers: wet edges break down, so repairs may be needed before resealing. Early action keeps it simple. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.

The price depends on the quantity of joints, how much old material needs removing and the access. Call for a fixed quote when you are ready.

Common problems we fix in Lower Earley

Adhesive failure, where the sealant peels away from one face, typically comes from poor preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond.

It’s worth sending us details if you spot any of the following:

  • Weathered joints at frame-to-structure perimeters
  • Gaps between rainscreen or cladding panels
  • Air leaks through failed facade joints
  • Weathered facade joints that have lost their grip

University estates such as University of Reading - Whiteknights Campus, 1.4 miles north-west of Lower Earley, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.

What your quote should include

  • Which product they’ll use, and why it suits the joint
  • Their plan for phasing and protecting the area
  • Their pre-qualification and accreditations
  • Whether primer will be used where the manufacturer specifies it

Choosing a commercial sealant contractor

What the job involves on each surface

Perimeter joints at frames and structure

The joint around a framed system, where it meets the structure, needs sealant. Our work is that perimeter joint, not the framing or glazing itself.

Render and coated surfaces

Rendered and painted facades need a sound edge for the sealant to bond to. Loose coatings are cleaned back first, and we will mention any edges that need repair.

From enquiry to sign-off

Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Work in places the size of Lower Earley is planned as a single visit where we can. Clear photos and measurements help us bring the right products.

  1. We look at the joints, the drawings and the access before pricing.
  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.

Preparing the site

  • Point out any areas we must not close
  • Explain the parking and delivery arrangements
  • Move anything stored against the joints

Facade sealing in Lower Earley: the local picture

The area within 2 miles of Lower Earley holds a number of hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack.

Hotels like Elmhurst Hotel, 1.3 miles north of Lower Earley, rarely close for long, so refurbishment mastic is phased floor by floor. When a college such as Bracknell & Wokingham College (to the north of Lower Earley) builds or refurbishes, the mastic package usually has to fit around students and staff.

Lower Earley is about 3 miles south-east of Reading, in Wokingham. Across the RG6 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Lower Earley is one of 42 places we cover in Wokingham.
