Facade sealing near Great Dunmow
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
What the job involves on each surface
Window and door perimeters
Perimeter joints move as frames expand and contract in the sun. Rod placed at the right depth lets the bead stretch without tearing.
Coping and flashing joints
Where the specification calls for sealant at copings or flashings, we can seal them. These joints take full exposure to weather, so preparation and product choice matter.
Facade sealing in Great Dunmow, done properly
Access is part of every facade job, and we plan it with you before quoting. Let us know what access exists or is planned, and any site rules we need to work around, so the price covers the real job. Site teams most often ask us about staining on stone next to old sealant and hard, chalky sealant that no longer flexes, across window and door perimeters, perimeter joints where frames meet the structure and cladding panel joints. One point of contact handles commercial sealant work in Great Dunmow from the first photographs to the final walk-round, for single jobs and planned programmes alike.
On a small site around Great Dunmow, the mastic is best done in the fewest visits we can manage. Tell us when scaffold comes down and when decoration finishes, and we’ll plan around those stages.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

On site: what to expect
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes a day or two for a few elevations, and longer where access has to be moved around the building, and we clear our waste as we work. If neighbouring businesses or buildings around Great Dunmow need work too, visits can be combined. Tell us your site hours and we will plan around them.
- First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- The completed runs are checked with you, then the 12-month guarantee applies.
Preparing the site
- Move anything stored against the joints
- Send asbestos survey details if the building is pre-2000
- Arrange parking or a loading space

New build and refits around Great Dunmow
Great Dunmow lies roughly 32 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. Great Dunmow is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack.
For contractors at a school such as Dunmow St Mary's Primary School, sealing has to be finished before term starts. Hotel extensions and refits, at places such as King's Head Hotel, which lies north-east of Great Dunmow, typically run between busy periods, so the sealing is squeezed into short windows. Units on estates such as Station Yard Industrial Park, 0.5 miles to the south-east of Great Dunmow, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
Great Dunmow is about 9 miles west of Braintree, in Essex. We cover Great Dunmow, with the same fixed quotes and 12-month guarantee as everywhere else. We work across 644 places in Essex, large and small. There’s a separate page for London, roughly 32 miles from Great Dunmow.

Common questions from Great Dunmow clients
Can you work at a site such as Station Yard Industrial Park, by Great Dunmow?

Can you work to our programme on a site in or near Great Dunmow?
Yes. The mastic is planned around your key stages. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day.
Do you guarantee your work?
Yes. Our workmanship is backed for 12 months on every job.
Do we need an asbestos check before resealing?
It’s worth checking in any building from before 2000. The duty to manage asbestos sits with the dutyholder, and we will ask to see it. If asbestos is suspected, work stops until it is tested.
Do you install glazing systems?
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.
What about RAMS and site documents?
Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.
How the quote is worked out
Quotes vary with the job. It mainly depends on:
- Working within restricted access windows
- Removal of failed or old sealant
- Any access equipment needed
- Site requirements such as inductions and permits
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.
Before you send an enquiry
The more we know, the firmer the quote. When you get in touch, include:
- Anything awkward about access or site hours
- What the building is and how it’s used
- When you need the work done
- Photos of the joints, close up and from further back
Need a figure for a tender or a budget? We’ll quote against your scope and drawings that you can work with. For a chat about it beforehand, call 01277 525 020 or send details through our quote form.
Leave it or put it right?
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. Small buildings around Great Dunmow suffer from failed joints as much as large ones. Catching it early means a reseal rather than repairs.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Work for main contractors and building owners
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
Aftercare for building managers
A few simple habits keep the new joints working:
- Investigate damp beside windows promptly
- Insist on a full cut-out when joints are renewed
- Check that rainwater leaves the facade the way it was designed to
- Confirm the survey covers external sealants in older buildings
Hold back any cleaning crew until the joints have had their stated cure time. Keep high-pressure jets and strong chemicals away from new sealant.
Use each reseal to correct the joint: the right width, backing rod and a sealant with enough movement capability. Repeating a faulty detail just repeats the failure.
