About our mastic sealing in Elmdon
Across Elmdon and the rest of Essex, we work the same way: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. Addresses, photos of typical joints and a rough idea of quantities let us give a quick quote or we can visit. If you are dealing with leaks at window and door perimeters and damaged joints in communal entrances and corridors, we can put it right, on shopfronts below residential blocks, window and door perimeters on blocks and external wall and movement joints alike. Most enquiries from Elmdon start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
In and around smaller places like Elmdon, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Common problems we fix in Elmdon
We often find joints filled solid with no backing rod, so the mastic is glued to the joint bottom too. It can’t stretch properly and it tears.
It’s worth sending us details if you spot any of the following:
- No planned programme for sealant
- Open joints in brickwork or panels
- Leaks at window and door perimeters
- Old repairs sealed over failed mastic
Older buildings near Elmdon, from historic houses such as Audley End House (3.9 miles east of Elmdon) to more modest stock, need compatible products when frames are resealed.
Questions to ask before you book
- What level of public liability insurance do they hold?
- Their approach to joint depth and backing
- Whether primer will be used where the manufacturer specifies it
- How the existing material will be dealt with
Surface by surface
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.
External movement joints
Joint size and product are matched to the expected movement, often around 2:1 width to depth, as the manufacturer advises.
What happens if it’s left?
Dealing with failed joints one report at a time is slow and scattered. A planned programme treats each building once and is simpler to manage and budget. Around Elmdon, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

Keeping the joints sound
To get the most from the new sealant:
- Encourage occupiers to report problems at frames
- Keep a record of when each building was resealed
- Check sealant joints during planned building inspections
- Prioritise elevations facing the weather
Include sealant in planned building inspections. Check for splits, open joints, brittle mastic and lifting edges, and note the building and elevation.
Left open, joint edges in render, brick or frames can deteriorate. Once that happens, repairs come before resealing and the job grows.
Cost factors for mastic joints
A fixed quote reflects the actual work. It takes account of:
- Access and working height
- Site requirements such as inductions and permits
- The total length or number of joints
- Location, for remote and island sites
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.
What to include in your enquiry
The more we know, the firmer the quote. Helpful details to send:
- Photos of the joints, close up and from further back
- Any dates the work must fit around
- Where the site is, with the postcode
- Asbestos survey details if the building is older
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, ring 01277 525 020 or email the details over.
Common questions from Elmdon clients
Will you take on a block within reach of Great Chesterford station?
Yes. Blocks of any size are within what we do. Send the address, photographs of the elevations and your access arrangements, and we will give a fixed quote.
Do you cover business parks and estates near Elmdon, such as Abbey Barns Business Park?
Yes. Our area takes in Elmdon and its surroundings, with estates and business parks such as Abbey Barns Business Park included. A few photographs and the unit address let us price the work.
How many days will you need on site?
That varies with the scale of the job, though a typical visit normally takes anything from a day to a few weeks, depending on the number of buildings and joints. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Can you take on resealing for a block portfolio?
Yes, that’s exactly who this service is for. We work through buildings in a planned order so you can plan around it.
Is asbestos a concern with old mastic?
Some mastics in pre-2000 buildings contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.
How do you handle work on occupied blocks?
Residents and tenants carry on as normal. If any flats or units need access, we’ll tell you in advance so you can arrange it with occupiers.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
How a job runs
Site rules come first: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, we take the joints in the sequence agreed with you. For work around Elmdon, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- We inspect the joints, building by building, and record what has failed and why.
- We send a fixed quote that sets out the joints, the products and the programme.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Getting the site ready
- Point out parking and an unloading spot
- Warn occupants and staff about the work
- Send asbestos survey details if the building is pre-2000
