About our facade sealing in Mashbury

We seal window and door perimeters, cladding panel joints, external facade joints and perimeter joints where frames meet the structure on offices, blocks and industrial units. Coping and flashing joints are included where sealant is the specified fix. If you are dealing with cold air coming in at window perimeters and weathered joints at frame-to-structure perimeters, we can help. A single leaking joint is often how a building in Mashbury first comes to us: we look at the rest while we are there and tell you what we find.

In the countryside around places like Mashbury, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Questions we’re asked in Mashbury

Could you schedule work at a campus like Writtle University College Cow Watering Campus for the vacation?

Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Do you take on work at healthcare sites like Broomfield Hospital?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

When can you be on site?

Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.

Do you replace failed glazing units?

No. Glazing, windows and glass replacement aren’t part of our work. We seal the joints around them, such as perimeter joints where frames meet the structure.

Can staff carry on working while you’re here?

Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.

How long does a job like this take?

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

Who decides which product is used?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Common problems we fix in Mashbury

Three-sided adhesion is a classic installation fault. With no backing, the sealant is restrained.

Any of the following is a good reason to get the joints checked over:

  • Draughts around frames and panels
  • Weathered joints at frame-to-structure perimeters
  • Unsightly perimeter sealant on a visible elevation
  • Leaks at window and door perimeters

On a healthcare site such as Broomfield Hospital, 3.3 miles east of Mashbury, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

What to look for in a quote

  • Do they follow the manufacturer’s priming guidance?
  • Can the work be phased to keep areas open?
  • Which product they’ll use, and why it suits the joint
  • How joint depth will be controlled

Choosing a commercial sealant contractor

Commercial clients in Mashbury

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules.

If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.

What we can’t put right

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Water getting in through cracked render or porous masonry
  • Work on the window or framing system itself
  • Arranging specialist high-level access, which is planned with the client

Not sure which it is? You can call 01277 525 020 or email us and we will tell you honestly.

Where we work in Mashbury

  • Window and door perimeters
  • Cladding panel joints
  • Stone and brick facade joints
  • Shopfront frames
  • Perimeter joints where frames meet the structure
  • Coping and flashing joints

Leave it or put it right?

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. Older rural buildings around Mashbury move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Why us?

  • One phone line for London, the South East and Scotland
  • Fully insured
  • Work carried out by CSCS-carded applicators
  • Failed material removed, not covered up

Facades, frames and programmes in Mashbury

Mashbury sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team. Mashbury is about 29 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, which keeps mastic packages in demand.

On a campus such as Writtle University College Cow Watering Campus (3.8 miles south of Mashbury), new teaching buildings and residences are usually built and refurbished around the academic year.

Mashbury is about 5 miles north-west of Chelmsford, in Essex. Businesses, contractors and managing agents in Mashbury use us for work on facade joints. Mashbury is one of 644 places in Essex on our list for facade joints. Sites around London have their own page, roughly 29 miles from Mashbury.

On site: what to expect

Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact. Rural sites near Mashbury may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. Product choice follows the joint’s movement and substrate.
  3. Failed beads are removed in full and both faces cleaned back.
  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.

Before we start on site

  • Warn occupants and staff about the work
  • Arrange parking or a loading space
  • Make sure the joints can be reached

Advice

What sets the cost

Each job is priced on its own details. The things that drive the figure:

  • Joint width, depth and condition
  • Which sealant the job calls for
  • The total length or number of joints
  • Whether old sealant has to be cut out first

What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a quote when you’re ready.

Details that help us quote

To price the job accurately, we need to understand the site. Useful things to include:

  • Drawings or a marked-up plan, if available
  • Photos of the joints, close up and from further back
  • The type of building and who uses it
  • Asbestos survey details if the building is older

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to phone 01277 525 020 or email us with what you know.
