Facade sealing in Wonersh

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. The enquiries we see most involve failed sealant on precast panel joints and weathered joints at frame-to-structure perimeters, on coping and flashing joints, window and door perimeters and cladding panel joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Wonersh it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

For a site near Wonersh, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Drawings, photos and the programme let us give a fixed quote.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Keeping the joints sound

A few simple habits keep the new joints working:

  • Check the asbestos register before old mastic is disturbed
  • Brief window cleaners about newly sealed joints
  • Note when each elevation was last resealed
  • Check that rainwater leaves the facade the way it was designed to

Following storms, look inside for damp or staining near frames. An early report normally means a small reseal rather than a bigger repair.

Building facade joints into a maintenance cycle avoids emergency repairs. Inspect regularly and reseal sections as they start to fail.

Do you need facade sealing in Wonersh?

Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.

Any of the following is a good reason to get the joints checked over:

  • Leaks at window and door perimeters
  • Discoloured or dirty facade joints
  • Gaps between rainscreen or cladding panels
  • Cold air coming in at window perimeters

Building work at universities like University of Surrey - Stag Hill Campus (to the north-west of Wonersh) is often timed for the summer, mastic included.

What to look for in a quote

  • Will failed sealant be removed rather than covered?
  • What level of public liability insurance do they hold?
  • Do they follow the manufacturer’s priming guidance?
  • Will CSCS-carded applicators be on site?

Questions to ask before you appoint anyone

Wonersh: questions and answers

Is Wonersh too small for you to travel to?

No. Places such as Wonersh are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Can you work at a site such as Broadford Business Park, by Wonersh?

Yes. We cover Wonersh and the area around it, including industrial estates, business parks and retail parks such as Broadford Business Park. Photos and a short description are enough for a first look.

Can the sealant be colour-matched?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.

How long will the new sealant last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Can you fit around our working hours?

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

Can you send site paperwork?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

Can you work while the building is occupied?

Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.

Doing it in-house

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Quoting for work in Wonersh

We price every job individually. The things that drive the figure:

  • How much existing material needs removing
  • The size and state of each joint
  • Location, for remote and island sites
  • Working within restricted access windows

A quote for facade joints depends on how many there are, their condition and the access, plus any specification you’re working to. Ask us for a fixed quote.

Details that help us quote

Good information means a firmer quote. Helpful details to send:

  • Where the site is, with the postcode
  • What the building is and how it’s used
  • Any specification or named product
  • Approximate linear metres or a joint schedule

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.

When it isn’t the sealant

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:

  • Render or concrete edges that have broken away
  • Specialist high-level access methods
  • Damp caused by condensation inside the building

Not sure which it is? You can give us a call on 01277 525 020 or email a schedule or drawings and we will tell you honestly.

Joints and surfaces we work on

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

Our process

Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. If others near Wonersh need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. First we review photos, 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. We walk the finished joints with you before handing over.

Preparing the site

  • Flag any permit to work we’ll need
  • Send any specification or drawings in advance
  • Clear stock, furniture or equipment away from the joints

Ask for a quote

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. The easiest way is to call 01277 525 020 or email a schedule or drawings.

Facade sealing in Wonersh: the local picture

The area within 2 miles of Wonersh holds a number of hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. Rainfall across the South East, Wonersh included, is lower than in many parts of the UK. 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.

Units on estates such as Broadford Business Park, 1.6 miles north-west of Wonersh, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
