Need facade sealing in West Reading?

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

What happens if it’s left?

Leaving failed perimeter sealant also makes the eventual job bigger: wet edges break down, so repairs may be needed before resealing. Early action keeps it simple. For buildings in places like West Reading, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.

The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Why appoint us

  • CHAS accredited
  • Colour agreed before work starts
  • Old sealant cut out, never sealed over
  • Workmanship guaranteed for 12 months

About our facade sealing in West Reading

External sealing depends on the weather more than most trades. Joints have to be dry and the air and surface temperature within the product’s range, so frosty or damp mornings can hold work back. We build that into the programme and tell you if the forecast changes the plan. If you have staining on stone next to old sealant and perimeter joints where frames meet the structure, we can put it right. Searching for sealant specialists in West Reading? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

Conversions around smaller places like West Reading often join new frames to old masonry or timber, and the sealant at those junctions has to cope with two materials that move differently, in a colour the planners or architect are happy with.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Building and refurbishing in West Reading

West Reading sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager. West Reading is about 39 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes.

For contractors at a college like Reading College (1.7 miles east of West Reading), perimeters and internal sealant are timed for the holidays. On a campus such as University of Reading, 1.5 miles to the east of West Reading, new teaching buildings and residences are typically built and refurbished around the academic year.

West Reading is about 1 mile north-west of Reading, in Reading. Businesses, contractors and managing agents in West Reading use us for work on facade joints, as part of our coverage of Reading. We work across 17 places in Reading.

Work on facade joints is covered throughout RG30, RG1 and RG31, for business premises of every kind. For a building on Lundy Lane, Wilson Road and Wilton Road or nearby, we can quote for facade joints. You’ll find West Reading on or near the A4, so getting applicators and materials to site is simple. Just outside West Reading, we also work in Coley Park (1 mile south-east), Reading (1 mile south-east), Caversham Heights (2 miles north), Lower Caversham (2 miles north-east) and Green Park (2 miles south).

Commercial clients in West Reading

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. West Reading can form part of a wider programme across Reading.

Maintenance after handover

Regular inspection catches problems early. Specifically:

  • Avoid patch repairs on failed facade joints
  • Report water ingress at frames as soon as it shows
  • Keep pressure washers away from fresh sealant
  • Walk the elevations once or twice a year

Hold back any cleaning crew until the joints have had their stated cure time. Keep high-pressure jets and strong chemicals away from new sealant, so brief your window cleaners.

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

Questions about West Reading

Do you cover business parks and estates near West Reading, such as Reading Retail Park?

Yes. Estates, retail parks and business parks around West Reading, Reading Retail Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

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

Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Are you insured?

Yes. Our insurance certificate can be sent alongside the quote.

Should we check old sealant for asbestos?

For older buildings, yes, check before work starts. The dutyholder holds the asbestos register, so ask for it before we start. If asbestos is suspected, work stops until it is tested.

Does the weather affect the work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Can you handle several sites?

Yes. Several buildings can share a single quote, with one point of contact.

Is colour matching possible?

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

Our process

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, and the work typically takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. If neighbouring businesses or buildings around West Reading need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full and the joint faces cleaned.
  4. Primer goes on where the product data asks for it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

Before we start on site

  • Tell staff and tenants when we’ll be in
  • Tell us what induction or permit system the site runs
  • For older buildings, check the asbestos register before work

Advice

Common problems we fix in West Reading

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.

These are often picked up first by site or facilities staff:

  • Sealant pulling away from frames or panels
  • Old perimeter mastic that has dried out
  • Failed seals around shopfront and entrance frames
  • Staining on stone next to old sealant

Hotels like Abbey House Hotel, less than half a mile to the south of West Reading, rarely close for long, so refurbishment mastic is phased floor by floor.

What your quote should include

  • Will CSCS-carded applicators be on site?
  • Will RAMS and insurance details be available?
  • How the existing material will be dealt with
  • Their public liability cover

How to choose a sealant contractor

Site staff or a sealant specialist?

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
