Facade sealing for New England sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Facade sealing in New England, done properly

Access is part of every facade job, and we plan it with you before quoting. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site. If you’re dealing with air leaks through failed facade joints and staining on stone next to old sealant, we can help. Facilities teams, main contractors and managing agents in New England tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

For a site near New England, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Drawings, photographs and the programme let us give a fixed quote.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

How a job runs

Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact. If others near New England need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full.
  4. Primer goes on where the product data asks for it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

Getting the site ready

  • Send your site hours and access windows
  • Send any specification or drawings in advance
  • Arrange parking or a loading space

Ask for a quote

A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or speak to us on 01277 525 020 or email drawings and photos if you’d rather talk the job through.

Advice

After the work

Cleaning and maintenance staff play a part too. Share these points with them:

  • Walk the elevations once or twice a year
  • Check that rainwater leaves the facade the way it was designed to
  • Brief window cleaners about newly sealed joints
  • Note when each elevation was last resealed

Blocked sills and gutters push water at the joints. Good drainage keeps water moving off the facade.

Coordinate facade sealing with other external works. Sharing the access keeps the cost down and limits disruption.

Contractors’ notes for New England

Central London is about 46 miles from New England. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes. Rainfall across the South East, New England included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager.

New units and refits on sites such as Blois Meadow Business Centre, 1.8 miles south-west of New England, need their panel and perimeter joints sealed to the specification. For contractors building in or near New England, we seal to the drawings, the specification and the programme.

New England is in Essex. Any commercial site in New England is covered, whether it’s a single job or part of a planned programme. Our Essex coverage takes in 644 places. For work in that direction, see our London page.

Questions we are asked in New England

Is New England too far out for you?

Not at all. New England is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Can the mastic package for our job in New England follow the site programme?

Yes. Send the programme and drawings, and we will plan the mastic to suit the stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

What hours do you work?

Mention the site’s hours and access windows in your enquiry, and we will plan around them. You can reach the office between 8am and 5pm, Monday to Friday.

Do you have public liability insurance?

Yes. Our insurance certificate can be sent alongside the quote.

Do you use silicone for external joints?

It depends on the joint, the substrate and any specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them and we follow the specified product.

How long before the joints can be used?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

Do you replace windows or glass?

No. That work needs a glazing specialist. We reseal window perimeters, panel joints and frame-to-structure perimeters on commercial buildings.

Surface by surface

Coping and flashing joints

Coping and flashing joints are included where sealant is the specified fix. They sit in the most exposed positions on the building and need a durable external sealant.

Brick and stone facades

On masonry, the sealant has to suit a porous, textured surface. Neutral-cure products are used because acetoxy types can mark some stone, with primer where its maker specifies.

Why act early in New England

Topping up a failed joint normally buys very little time. A full cut-out and fresh bead is the repair that holds and avoids repeat call-outs. For buildings around smaller places like New England, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

A quote for facade joints depends on quantities, condition and access. Call for a quote.

What sets the cost

A fixed quote reflects the actual work. It takes account of:

  • Quantities, in metres or numbers
  • How much existing material needs removing
  • The product specified
  • Working within restricted access windows

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

Details that help us quote

It doesn’t need to be a full survey. A few details are enough to get going:

  • Your programme or deadline
  • Drawings or a marked-up plan, if available
  • Anything awkward about access or site hours
  • Specification clauses that apply

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.
