Facade sealing for Burnt Heath sites

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Surface by surface

Cladding panel joints

Joints between cladding panels open and close with temperature. We use a product rated for the movement and suited to the panel surface, as the specification sets out.

Window and door perimeters

Aluminium, PVC-U and timber frames each have their own preparation needs. We clean and prime to the sealant maker’s guidance for each surface.

Facade sealing in Burnt Heath

External joints face UV, rain, temperature swings and building movement all year, and they wear out over time. 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. The enquiries we see most involve water coming in around window frames and air leaks through failed facade joints, across shopfront frames, perimeter joints where frames meet the structure and stone and brick facade joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Burnt Heath it comes down to the same thing: the right product in a properly prepared joint.

In the countryside around places like Burnt Heath, 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 typically what’s needed.

Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

Common questions from Burnt Heath clients

Is Burnt Heath too far out for you?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Can you work on a hospital site such as Colchester Hospital?

Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.

Do you have public liability insurance?

Yes. We are fully insured, including public liability cover.

Is colour matching possible?

That depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

What type of sealant goes on window perimeters?

Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others.

Do you seal on top of existing sealant?

No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Do you replace windows or glass?

No. We don’t install glazing systems, windows or glass. We seal the joints around them, including perimeters where frames meet the structure.

Contractors’ notes for Burnt Heath

Burnt Heath sits in one of the drier corners of the country, the South East. 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. Central London is about 55 miles from Burnt Heath. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme.

Historic houses such as Castle House, 2.6 miles north of Burnt Heath, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. Hospital estates such as Colchester Hospital, 4.4 miles west of Burnt Heath, 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.

Burnt Heath is about 5 miles east of Colchester, in Essex. Across the CO7 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Burnt Heath is one of 644 places we cover in Essex for facade joints. For work in that direction, see our London page, about 55 miles away.

Work for main contractors and building owners

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Diagnose, treat, sign off

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself usually taking anything from a single day to several weeks, depending on joint lengths, access and the weather. Jobs in and around smaller places like Burnt Heath are typically planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. We start with photographs, drawings or a visit to see the joints and agree access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out in full.
  4. Primer is applied where the maker specifies 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
  • Share the asbestos register for older buildings
  • Tell us which areas need to stay in use

Quotes

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Advice

What sets the cost

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

  • Location, for remote and island sites
  • Access and working height
  • Removal of failed or old sealant
  • The site’s rules and procedures

The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Sending details for a quote

There’s no need for a formal survey. A few details are enough to get going:

  • Anything awkward about access or site hours
  • Any specification or named product
  • Your programme or deadline
  • Whether the building will be occupied during the work

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, call 01277 525 020 or send photos by email.

What sealant work can’t fix

Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:

  • Replacing glass or failed glazing units
  • Specialist high-level access methods
  • Movement beyond what any sealant can handle

If in doubt, call 01277 525 020 or use the quote form and we will say what we think.

What we seal

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

Do you need facade sealing in Burnt Heath?

Overlaying old sealant is a common shortcut that fails quickly. Fresh silicone won’t stick to cured silicone.

It’s worth sending us details if you spot any of the following:

  • Patch repairs that keep failing
  • Air leaks through failed facade joints
  • Damp patches beside frames after rain
  • Weathered joints at frame-to-structure perimeters

Units on estates such as Martells Industrial Estate, 1.1 miles west of Burnt Heath, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Before you book anyone
