Mastic sealing in Colchester
In buildings from before 2000, some old mastics contain asbestos. Before we disturb it, we ask to see the asbestos register or survey and if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. Site teams most often ask us about draught complaints from residents or tenants and communal area joints that look neglected, across balcony and threshold joints, window and door perimeters on blocks and external wall and movement joints. A specialist sealant contractor works differently from a general builder: in Colchester, that means joint design, primers and backing rod as standard.
Town-centre blocks over shops in places like Colchester have frames, balconies and communal entrances with mastic to maintain. A failed joint can let water into a flat or the unit below, so it pays to renew mastic before it leaks.
Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.
How a job runs
Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Sites in a big town such as Colchester frequently have reception sign-in, inductions and permits to work. Send the site rules with your enquiry and we will plan to them.
- We check the asbestos register for older buildings and look at the joints.
- A fixed quote covers the joints, products and order of work.
- Failed mastic is removed completely.
- Joint faces are cleaned, backed and resealed.
- We finish each building before moving to the next.
What we need from you
- Have the specification and drawings to hand
- Send your site hours and access windows
- For older buildings, check the asbestos register before work
Quotes
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.

Questions about Colchester
Will you take on a block within reach of Colchester Town station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photographs of the elevations and your access arrangements, and we’ll give a fixed quote.
Do you cover business parks and estates near Colchester, such as Colchester Retail Park?
Yes. Our area takes in Colchester and its surroundings, with estates and business parks such as Colchester Retail Park included. To start, just speak to us on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Can you plan resealing across several buildings?
Yes, planned programmes suit estates and portfolios. The quote can be split however suits your budgeting.
Which sealant will you use?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Do you check for asbestos in old sealant?
We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.
What about access for upper-floor joints?
Access is discussed and agreed before the quote is fixed. Tell us the building height and any access already in place and we will confirm the approach in the quote.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Common problems we fix in Colchester
We often find joints filled solid with no backing rod so the mastic is bonded on three sides. That three-sided adhesion stops it stretching and it tears.
These are often picked up first by site or facilities staff:
- Movement joints with sealant missing
- Occupiers reporting cold air round windows
- Water getting in round frames after rain
- Cracked, hardened mastic round windows on a block
For owners of several units at places like Colchester Retail Park (under half a mile north-west of Colchester), one programme can deal with frame and external mastic across the lot.
What to look for in a quote
- How they’ll work around occupants
- What level of public liability insurance do they hold?
- Which product they’ll use, and why it suits the joint
- Will failed sealant be removed rather than covered?

Different surfaces, different methods
Tenement and older buildings
Stone needs a neutral-cure product, so we pick a grade that won’t mark it.
Window and door perimeters on blocks
Window and door perimeters are where most mastic failure shows. We remove the failed mastic, prepare the faces, add backing rod if the joint is deep and reseal.
Why act early in Colchester
Failed perimeter mastic lets cold air in around frames and the windows normally get the blame. Resealing the perimeters is often the simpler fix when the frames themselves are sound. If one joint has failed on your building in Colchester, others of the same age may be close behind. Renewing them in one programme saves time later.

Looking after buildings in and around Colchester
The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building usually need attention first. Central London is about 50 miles from Colchester. Within reach of London, blocks run by agents and associations are common around stations, and window and balcony mastic on them tends to age at the same rate.
Site managers at schools like Colchester Sixth Form College can fit frame mastic into the summer works. Owners of student blocks near University of Essex, 2.2 miles to the south-east of Colchester, can schedule frame and external mastic for the summer vacation.
Colchester is in Essex. Anywhere in CO4, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Colchester is one of 644 places we cover in Essex for mastic joints. There’s a separate page for London, roughly 50 miles from Colchester.
If you need mastic sealing in CO4, CO3, CO2 and CO1, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. Streets here include High Street, North Station Road and Durham Square. You will find Colchester on or near the A12 and A120, so getting applicators and materials to site is simple. Just outside Colchester, we also work in Camulodunum (1 mile west), Braiswick (1 mile west), Abbey Field (1 mile south), Lexden (1 mile west) and Beacon End (3 miles west). Nearby towns on our patch include Braintree (14 miles west), Clacton-on-Sea (12 miles south-east), Maldon (15 miles south-west), Witham (13 miles south-west), Halstead (12 miles west) and Heybridge (14 miles south-west). Among the larger centres in Essex is Colchester, and we take on mastic joints for its commercial and public buildings.
Around Colchester
Around Colchester, our work takes us to commercial buildings near Bull Meadow, The Bay And Say Public House and St John's Green Primary School, among other places. There’s a railway station in Colchester itself: Colchester Town station. A little further out are Lion Walk (under half a mile south-east) and Essex County Hospital (under half a mile south-west). For a walk, there’s Westhouse Wood.
Keeping the joints sound
After handover, these steps help:
- Mention RAMS, insurance or CSCS requirements up front
- Have the asbestos survey to hand for older buildings
- Reduce knocks to communal area joints
- Encourage occupiers to report problems at frames
If a joint we sealed fails within 12 months, tell us and we’ll look at it. Beyond that, routine checks spot the next round of repairs.
Left open, joint edges in render, brick or frames can deteriorate. Then the edges may need repairing first and the job grows.
Cost factors for mastic joints
Quotes vary with the job. It mainly depends on:
- Access and working height
- Whether the work must be split into stages
- Specialist products, such as fire-rated or hygienic sealants
- Distance, for remote addresses
Pricing mastic joints depends on quantities, condition and access, plus any specification you are working to. Call for a quote.
Sending details for a quote
Good information means a firmer quote. When you get in touch, include:
- When you need the work done
- Rough lengths or quantities, or drawings if you have them
- Where the site is, with the postcode
- Whether the building will be occupied during the work
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.
