Facade sealing across Nash Street

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

Keeping the joints sound

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Add perimeter sealant to planned maintenance checks
  • Never let anyone seal over old sealant
  • Plan facade sealing alongside redecoration
  • Report water ingress at frames as soon as it shows

After heavy weather, check vulnerable elevations for signs of water inside. Catching a new leak early keeps the repair small.

Tie resealing in with redecoration, cladding repairs or other access. Sharing the access keeps the cost down and limits disruption.

Facade sealing in Nash Street

Every facade quote starts with how the joints will be reached. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site, so the price covers the real job. We work on window and door perimeters, shopfront frames and cladding panel joints, and what we’re called in for most is discoloured or dirty facade joints and perimeter sealant that has split or peeled away. Facilities teams, main contractors and managing agents in Nash Street tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

In the countryside around places like Nash Street, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is usually what’s needed.

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

On site: what to expect

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before we move to the next. Jobs in and around smaller places like Nash Street are typically planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out in full and the joint faces cleaned.
  4. Primer goes on where the product data asks for it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

Before we start on site

  • Send your site hours and access windows
  • Flag any permit to work we’ll need
  • Confirm the product named in the specification

Doing it in-house

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Quoting for work in Nash Street

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • Site requirements such as inductions and permits
  • Travel to remote or island sites
  • Specialist products, such as fire-rated or hygienic sealants
  • How much there is to seal

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

What to include in your enquiry

Diagnosis starts before we arrive. Let us know:

  • The postcode of the building
  • Your programme or deadline
  • What the building is and how it’s used
  • The asbestos register, for older buildings

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

Questions we’re asked in Nash Street

Is Nash Street too small for you to travel to?

No. Places such as Nash Street are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

Can work at a site such as University of Greenwich fit around teaching?

Yes, holiday working periods are the norm on campus jobs. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Can you work while the building is occupied?

Yes, with some planning. Tell us your site hours and access windows and we will plan around them.

Can you send site paperwork?

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

Are you CHAS accredited and on Constructionline?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Will you quote for a small job?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Can you handle several sites?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

Do you need facade sealing in Nash Street?

Not every failure is in the sealant: if the edge of the render, concrete or coating breaks away, the bead goes with it. We tell you when the edges need repairing before resealing.

If one of these sounds familiar, it’s time for a closer look:

  • Perimeter joints where frames meet the structure
  • Water coming in around window frames
  • Old perimeter mastic that has dried out
  • Air leaks through failed facade joints

New wings at hospitals like Gravesham Community Hospital (to the north of Nash Street) bring long runs of window and panel joints to seal.

Questions to ask before you book

  • How they’ll work around occupants
  • Which product they’ll use, and why it suits the joint
  • How the joint faces will be prepared and primed
  • What the guarantee covers, and for how long

Choosing a commercial sealant contractor

Surface by surface

Coping and flashing joints

Coping and flashing joints are included where sealant is the specified fix. These joints take full exposure to weather, so preparation and product choice matter.

Cladding panel joints

On sealed panel systems, every joint keeps water out. Failed runs are cut out and rebuilt end to end with backing and a facade-grade sealant.
