Facade sealing near Westwood

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

Facade sealing in Westwood, done properly

External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits, and cold, damp starts can delay work. We plan for that and keep you updated. Most enquiries involve unsightly perimeter sealant on a visible elevation and old perimeter mastic that has dried out, across stone and brick facade joints, shopfront frames and window and door perimeters. Facilities teams, main contractors and managing agents in Westwood tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

On a small site around Westwood, the mastic is best done in the fewest visits we can manage. Tell us when scaffold comes down and when decoration finishes, and we will plan around those stages.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Your questions answered

Is Westwood too far out for you?

No. Small places get the same service as large ones. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.

Could you schedule work at a campus like Nelson College London for the vacation?

Yes. Education sites normally 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 will confirm them alongside the quote.

Are you CHAS accredited?

Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.

Will you check whether the sealant is causing the leak?

Yes. We look at the perimeter sealant and tell you whether it has failed as part of pricing. If the water seems to come from a roof, sill or the glazing unit instead, we say so.

Will you come and look before quoting?

That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.

Can you work on upper floors?

Access is planned with you before we quote. Tell us about access: existing scaffold, what you’re arranging and any site restrictions, and the quote will reflect it.

Will you just go over the old sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Facade sealing in Westwood: the local picture

With the shore within about 2 miles, Westwood counts as a coastal location. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Westwood lies roughly 65 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme.

Work at a hotel such as Former 'Man Of Kent' Temperance Hotel, 1.2 miles to the north of Westwood, tends to be programmed around bookings, mastic included. When units on a site such as Westwood Industrial Estate, less than half a mile east of Westwood, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Westwood is about 1 mile south of Margate, in Kent. Businesses, contractors and managing agents in Westwood use us for work on facade joints, as part of our coverage of Kent. We work across 931 places in Kent, from busy centres to rural villages. London is covered too, around 65 miles from Westwood.

We cover the CT9 and CT10 postcode districts for facade joints. For a building on Leo Road, Nash Road and Luna Road or nearby, send details and we will quote for facade joints. Access to Westwood is via the A254 among other routes, so getting applicators and materials to site is simple. Close to Westwood, our area also takes in Flete (1 mile west), Haine (1 mile south), Margate (1 mile north), Newington (1 mile south) and Garlinge (2 miles north-west). A short drive away, we cover Canterbury (15 miles south-west), Whitstable (15 miles west), Deal (10 miles south), Herne Bay (11 miles west), Walmer (11 miles south) and Wincheap (15 miles south-west).

A little further out are Public Library & Museum (Camborne) (1.4 miles north) and Queen Elizabeth the Queen Mother Hospital (0.7 miles north). The countryside around Westwood includes Sandwich and Pegwell Bay.

Looking after the joints

Keep the joints in good shape with a few simple steps:

  • Clear debris that holds water against joints
  • Check the asbestos register before old mastic is disturbed
  • Avoid patch repairs on failed facade joints
  • Keep pressure washers away from fresh sealant

Let the new sealant cure before washing the facade or windows near it. Keep high-pressure jets and strong chemicals away from new sealant.

Get the joint design right when resealing: correct depth, proper backing and a sealant that can take the movement. A well-designed joint lasts longer than a like-for-like copy of a failed one.

Why it’s worth doing now in Westwood

Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Leaks travel along the structure. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Why us?

  • Public liability insurance in place
  • One phone line for London, the South East and Scotland
  • A range of standard colours, depending on the product
  • 12-month guarantee on workmanship

What sets the cost

Before we quote, we look at:

  • Location, for remote and island sites
  • Backing rod, priming and other preparation
  • Removal of failed or old sealant
  • Access and working height

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

Before you send an enquiry

A few photographs plus some basic facts will normally do. It helps to include:

  • A wide shot and a close-up of the area
  • Whether an asbestos survey exists
  • Any specification or named product
  • Whether the building will be occupied during the work

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.

Common problems we fix in Westwood

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

Clients typically get in touch after noticing one or more of the following:

  • Patch repairs that keep failing
  • Weathered facade joints that have lost their grip
  • Unsightly perimeter sealant on a visible elevation
  • Failed seals around shopfront and entrance frames

For a contractor working at a hospital such as Queen Elizabeth The Queen Mother Hospital, 0.7 miles north of Westwood, perimeter and facade sealing is planned around patients and deliveries.

Comparing quotes

  • Whether their applicators hold CSCS cards
  • Their plan for phasing and protecting the area
  • Whether old or failed sealant will be cut out, not overlaid
  • Do they follow the manufacturer’s priming guidance?

Our contractor checklist

How a job runs

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. What matters most for a job in Westwood is a clear list of what needs doing, so send photos of each area. A fixed quote follows.

  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. We walk the finished joints with you before handing over.

Getting the site ready

  • Explain the parking and delivery arrangements
  • Send your site hours and access windows
  • Share the asbestos register for older buildings

What the job involves on each surface

Precast concrete panels

Concrete edges can be dusty or weak. Faces are cleaned to sound concrete, and damaged edges are reported before sealing.

Perimeter joints at frames and structure

These frame-to-structure joints take a lot of movement and weather. We cut them out, prepare both faces and reseal to the specification using a sealant classified for that use.
