Facade sealing for businesses in Long Green

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

Our process

At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. For work around Long Green, we aim to finish in one 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. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full.
  4. Primer is applied where the maker specifies it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. We go over the completed work with you before leaving.

Before we start on site

  • Warn occupants and staff about the work
  • Flag any permit to work we’ll need
  • Confirm the product named in the specification

Advice

Facade sealing in Long Green

Facade sealants sit in the sun, rain and frost every day, so they don’t last indefinitely. Life depends on movement, weathering, product choice and the quality of the original work. When the time comes, we cut the old sealant out completely and start again. We work on shopfront frames, stone and brick facade joints and coping and flashing joints, and the usual reasons a site gets in touch are cold air coming in at window perimeters and sealant pulling away from frames or panels. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Long Green is the same: the right product in a properly prepared joint.

In the countryside around places like Long Green, 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 normally what’s needed.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Long Green: questions and answers

Is Long Green too small for you to travel to?

No. Places such as Long Green are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Can you work on a hospital site such as Braintree Community Hospital?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Is your workmanship covered by a guarantee?

Yes. The 12-month guarantee covers our preparation and application, though not damage or work by other trades.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards, as many construction sites ask for.

Is colour matching possible?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.

How long do sealant joints last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Cost factors for facade joints

There’s no standard rate for sealant work, since sites vary so much. What we take into account:

  • The site’s rules and procedures
  • How accessible the joints are
  • How much there is to seal
  • Phasing around occupants

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Before you send an enquiry

For an accurate fixed quote, we need to understand the site. Send us:

  • Whether the building will be occupied during the work
  • Access details, including height
  • A wide shot and a close-up of the area
  • Whether an asbestos survey exists

For a fixed quote, call the office on 01277 525 020 or send photos by email with the site address and an outline of the work. Our quote form is another easy route.

Honest limits

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • Render or concrete edges that have broken away
  • Specialist high-level access methods
  • Damp caused by condensation inside the building

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

Surfaces we seal

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

Why it’s worth doing now in Long Green

Each spell of rain drives water past a failed facade joint. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing now costs less than repairing interiors later. Older rural buildings around Long Green move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

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

Why us?

  • One number for every site we cover
  • A range of standard colours, depending on the product
  • Specification-led, product-correct work
  • Colour agreed before work starts

Sites and facades in and around Long Green

Long Green is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager. Long Green lies roughly 39 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme.

Projects at schools like Cressing Primary School work to term dates, so mastic is programmed tightly. Hospital estates such as Braintree Community Hospital, 2.2 miles to the north-west of Long Green, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

Long Green is about 2 miles south-east of Braintree, in Essex. Long Green sits inside our coverage and the rest of Essex, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Across Essex, 644 places are covered, Long Green among them.

When to call us in Long Green

Most facade joints fail through age and weathering. The bead hardens, chalks on the surface and loses the flexibility to follow the joint, then it splits or peels.

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

  • Old perimeter mastic that has dried out
  • Damp patches beside frames after rain
  • Sealant pulling away from frames or panels
  • Weathered joints at frame-to-structure perimeters

For contractors refurbishing units at places like Lanham Business Park (0.6 miles east of Long Green), the mastic covers cladding panels, roller-door and window perimeters.

What to look for in a quote

  • Their pre-qualification and accreditations
  • What level of public liability insurance do they hold?
