Do you need facade sealing in Ewell?

Sometimes the substrate is the problem: crumbling render, spalling concrete or flaking paint take the sealant with them. We tell you when the edges need repairing before resealing.

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

  • Previous reseals run over old sealant
  • Sealant pulling away from frames or panels
  • Hard, chalky sealant that no longer flexes
  • Damp patches beside frames after rain

University estates such as University for the Creative Arts (to the south of Ewell) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.

Questions to ask before you book

  • How the existing material will be dealt with
  • Will CSCS-carded applicators be on site?
  • Are they CHAS accredited or on Constructionline?
  • Their approach to joint depth and backing

How to choose a sealant contractor

How we handle facade sealing in Ewell

We are often asked to look at water coming in around frames. Failed perimeter sealant is a frequent cause, though that isn’t the only cause. If the evidence points away from the sealant, we say so before quoting. Site teams most often ask us about patch repairs that keep failing and perimeter sealant that has split or peeled away, across coping and flashing joints, cladding panel joints and perimeter joints where frames meet the structure. Facilities teams, main contractors and managing agents in Ewell tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

In towns like Ewell, sites are normally modest: small housing schemes, extensions to schools and surgeries, refurbished shops and offices. The perimeter and facade joints on a small scheme need the same sizing and preparation as on a big one.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

After the work

For the best life from the joints:

  • Record the product and colour used on each elevation
  • Check the asbestos register before old mastic is disturbed
  • Insist on a full cut-out when joints are renewed
  • Add perimeter sealant to planned maintenance checks

Hold back any cleaning crew until the joints have had their stated cure time. Pressure washers and harsh cleaners can damage a fresh bead and tell your cleaning contractor.

Coordinate facade sealing with other external works. One set-up for several trades saves money and cuts time on site.

On site: what to expect

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself normally taking anything from a single day to several weeks, depending on joint lengths, access and the weather. Town-centre premises in Ewell may have limited parking, so tell us what’s nearby. Industrial and business units usually have yard or car park space.

  1. We look at the joints, the drawings and the access before pricing.
  2. Failed sealant is cut out along its full length.
  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.

Getting the site ready

  • Tell us what induction or permit system the site runs
  • Point out any areas we must not close
  • Clear stock, furniture or equipment away from the joints

Why it’s worth doing now in Ewell

The longer a failed joint is left, the more the substrate suffers: edges get wet, render and timber deteriorate and frames can move. Early action keeps it simple. In a town like Ewell, a split, stained or mouldy joint is often the first thing visitors notice. Fresh sealant makes a building look maintained.

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

Why clients in Ewell choose us

  • Colours chosen to suit frames, cladding or finishes where possible
  • Products installed to the manufacturer’s instructions
  • Colour agreed before work starts
  • A Constructionline member, so easy to vet

Facades, frames and programmes in Ewell

A 2-mile radius around Ewell takes in a number of hotels. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight. Ewell lies roughly 12 miles out from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme.

Work at a hotel such as Spring Hotel, less than half a mile south-east of Ewell, tends to be programmed around bookings, mastic included. Projects at colleges like North East Surrey College of Technology, 1 mile to the south-east of Ewell, tend to run to term dates, so the mastic is planned tightly.

Common questions from Ewell clients

Can you take on a job at a hospital such as St. Ebba's Hospital?

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

Can you work at a site such as Longmead Industrial Estate, by Ewell?

Yes. Estates, retail parks and business parks around Ewell, Longmead Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

What about RAMS and site documents?

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

Can you quote from photographs?

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.

How many days will you need on site?

We plan the time on site around your programme and access. You will have an expected duration with the quote.

Do your applicators hold CSCS cards?

Yes. If you need card details for site access, let us know and we’ll send them with the quote.

Can the building stay open while you work?

In most cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.

What sets the cost

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

  • The size and state of each joint
  • Removal of failed or old sealant
  • Which sealant the job calls for
  • Quantities, in metres or numbers

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.

Before you send an enquiry

To price the job accurately, we need a clear picture of the site. Send us:

  • The postcode of the building
  • Rough lengths or quantities, or drawings if you have them
  • Asbestos survey details if the building is older
  • A wide shot and a close-up of the area

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.

Work for main contractors and building owners

Building owners and managing agents use us on everything from one building to a spread of sites around Ewell. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
