About our facade sealing in Woodcote Green

External joints face UV, rain, temperature swings and building movement all year. Life depends on movement, weathering, product choice and the quality of the original work. When the time comes, we cut the old sealant out completely and start again. We work on window and door perimeters, perimeter joints where frames meet the structure and shopfront frames, and the failures we are asked to look at most are perimeter sealant that has split or peeled away and hard, chalky sealant that no longer flexes. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Woodcote Green, preparation and product choice get the time they need.

Every London site, Woodcote Green included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Alongside that, sites usually need booked deliveries and a plan for where materials go.

We stand by our work with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

On site: what to expect

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. All of Greater London is in the ULEZ, and kerbside space in Woodcote Green can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. The old bead is cut away completely, not overlaid.
  3. Both faces are cleaned and, where the product needs it, primed.
  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

  • Clear stock, furniture or equipment away from the joints
  • For older buildings, check the asbestos register before work
  • Tell staff and tenants when we will be in

Advice

Why act early in Woodcote Green

Failed joints let in more than water: occupants notice draughts and cold spots around windows. Resealing deals with the draught as well as the leak. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Why us?

  • Colour options checked against the specified product
  • Health and safety: CHAS accredited
  • CSCS-carded applicators
  • Sealing commercial buildings since 2005

Common problems we fix in Woodcote Green

Overlaying old sealant is a common shortcut that fails quickly. Cured silicone won’t accept a new silicone bead, and the patch soon lifts.

Site and facilities staff are often the first to spot these:

  • Failed seals around shopfront and entrance frames
  • Previous reseals run over old sealant
  • Gaps between rainscreen or cladding panels
  • Discoloured or dirty facade joints

Projects at schools like Wallington High School for Girls work to term dates, so mastic is programmed tightly.

Comparing quotes

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Is the sealant right for the movement and the substrate?
  • What the guarantee covers, and for how long
  • How the joint faces will be prepared and primed

Questions to ask before you appoint anyone

Building and refurbishing in Woodcote Green

Several hotels sit less than 2 miles from Woodcote Green. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight. Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Woodcote Green. Deliveries are booked and storage is tight, so mastic materials come in as needed.

On a healthcare site such as Purley War Memorial Hospital (1.5 miles east of Woodcote Green), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. When a college such as Purley Language College (1.3 miles east of Woodcote Green) builds or refurbishes, the mastic package normally has to fit around students and staff.

Woodcote Green is about 1 mile west of Purley, in Greater London. We cover commercial sites throughout Woodcote Green, whether it’s a single job or part of a planned programme. Woodcote Green is one of 764 places we cover in Greater London. We also cover London, around 11 miles from Woodcote Green.

Anyone looking for facade sealing in CR8, SM6 and SM5 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee.

Just outside Woodcote Green, we also work in Little Woodcote (1 mile west), Woodcote (1 mile south-east), Peaks Hill (1 mile east), Roundshaw (1 mile north-east) and Russell Hill (1 mile north-east). Bigger towns within reach include London (11 miles north), City of Westminster (12 miles north), Marylebone (12 miles north), Kensington (11 miles north), St Pancras (13 miles north) and Shoreditch (13 miles north).

Different surfaces, different methods

Precast concrete panels

Concrete edges can be dusty or weak. We clean back to sound material and flag edges that need repair.

Render and coated surfaces

Sealant can only hold as well as the render or paint beneath it. We remove flaking material so the bead bonds to a firm surface, and areas needing repair are flagged.

Common questions from Woodcote Green clients

Can you work in a London building with booked loading and goods-lift slots?

Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. We allow for the ULEZ, which covers every borough

Will you plan work around the academic year at somewhere like University for the Creative Arts - Epsom?

Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

How long does a job like this take?

That varies with the scale of the job, though a typical visit usually takes anything from a single day to several weeks, depending on joint lengths, access and the weather. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Do you need to see the site first?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.

Do we need an asbestos check before resealing?

In older non-domestic buildings, old sealant can contain asbestos. Check the asbestos register or survey before it is disturbed. We don’t remove asbestos-containing materials.

What sets the cost

What shapes the price:

  • Distance, for remote addresses
  • The size and state of each joint
  • Which sealant the job calls for
  • Quantities, in metres or numbers

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Sending details for a quote

Diagnosis starts before we arrive. Let us know:

  • The postcode of the building
  • A wide shot and a close-up of the area
  • Approximate linear metres or a joint schedule
  • Whether the building will be occupied during the work

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or call the office on 01277 525 020 or send photos by email to discuss it first.

Owners, agents and contractors

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.
