How the job changes by surface

Render and coated surfaces

Paintable sealants exist for joints that will be coated. We confirm the product with you before starting.

Precast concrete panels

Joints between precast panels carry real movement. We use a sealant with the right movement capability, set over backing rod.

How we handle facade sealing in Putney Vale

Some clients need every window on a block resealed; others need a few leaking frames sorted. Either way, the method is the same: old sealant out, faces cleaned, depth set and a new bead tooled in. A 12-month guarantee applies to our workmanship. The enquiries we see most involve failed seals around shopfront and entrance frames and perimeter sealant that has split or peeled away, across coping and flashing joints, shopfront frames and window and door perimeters. A single leaking joint is often how a building in Putney Vale first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Common problems we fix in Putney Vale

Three-sided adhesion is a classic installation fault. With no backing, the sealant is restrained and rips when the facade moves.

Common reasons buildings call us in:

  • Facade joints cracked through the middle
  • Staining on stone next to old sealant
  • Gaps between rainscreen or cladding panels
  • Water coming in around window frames

For contractors at a college like Wimbledon College of Arts, 2.2 miles south-east of Putney Vale, perimeters and internal sealant are timed for the holidays.

Questions to ask before you appoint anyone

Doing it in-house

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Why deal with it now?

Each spell of rain drives water past a failed facade joint. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing now costs less than repairing interiors later. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.

The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote when you’re ready.

What sealant work can’t fix

Being straight saves everyone time. New sealant won’t cure:

  • Specialist high-level access methods
  • Damp caused by condensation inside the building
  • Installing or repairing glazing systems

FAQs: Putney Vale

Is hospital work, at somewhere like New Victoria Hospital, something you do?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Does your area include sites such as Rainbow Industrial Estate, near Putney Vale?

Yes. Our area takes in Putney Vale and its surroundings, with estates and business parks such as Rainbow Industrial Estate included. To start, just speak to us on 01277 525 020 or email us with the unit, the joints involved and your access times.

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 run new sealant over the existing bead?

No. A bead run over old sealant soon lifts. Our method is a full cut-out, cleaning, backing and a new bead.

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators.

Can you send site paperwork?

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

How long does a job like this take?

The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.

Facade sealing in Putney Vale: the local picture

London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for. A 2-mile radius around Putney Vale takes in a number of hotels. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight.

Extensions at sites like New Victoria Hospital, 1.3 miles south of Putney Vale, typically sit beside working departments, and the mastic follows strict access rules.

From enquiry to sign-off

Before we leave any area, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Planning a London job such as one in Putney Vale starts with access. Give us the hours we can be on site and we will schedule to suit.

  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. The new sealant goes in and is tooled firmly onto both faces.
  6. We walk the finished joints with you before handing over.

Preparing the site

  • Tell us which areas need to stay in use
  • Share the asbestos register for older buildings
