How we handle mastic sealing in Eynsham
Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. A planned, building-by-building programme often works better than reacting to each complaint and we quote and schedule each building in turn. Site teams most often ask us about worn sealant at communal door frames and water getting in round frames after rain, on external wall and movement joints, communal kitchens and washrooms and communal entrances and stairwells. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Eynsham, preparation and product choice get the time they need.
Owners with buildings around smaller places like Eynsham often group mastic work so one visit covers several properties. One quote can cover a whole list of addresses.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Questions we are asked in Eynsham
Is Eynsham off your patch?
No. Small places get the same service as large ones. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
Do you work for managing agents with blocks near Hanborough station?
Yes, and several blocks can go on one quote. We work to your notice and access arrangements.
Can you send RAMS and CSCS details before starting?
We’re CHAS accredited, a Constructionline member and carry public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.
Do you do block-wide mastic programmes?
Yes, planned programmes suit estates and portfolios. You get a fixed quote per building or for the whole job.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
How do you reach windows on upper floors?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned and we’ll confirm the approach in the quote.
When it isn’t the sealant
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
- Failed window or door frames, which need a window contractor
If you’re not sure, just give us a call on 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.

On site: what to expect
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. For a site in Eynsham, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.
- Each block or building is walked and the failed joints recorded with the likely cause.
- We send a fixed quote that sets out the joints, the products and the programme.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- Old sealant is stripped and each face prepared back to firm material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Before we start on site
- Send your site hours and access windows
- Tell staff and tenants when we will be in
- Send asbestos survey details if the building is pre-2000

Advice
Planned mastic for Eynsham portfolios
Eynsham sits in one of the drier corners of the country, the South East. Outside work still depends on dry joints, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first. Eynsham lies roughly 58 miles out from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres, and window and balcony mastic on them tends to age at the same rate.
Buildings close to stations like Hanborough station (2.9 miles north of Eynsham) are often flats over shops, with frame mastic to keep sound. Older community buildings, Church of St Leonard among them, often have frames of mixed ages whose mastic varies.
Eynsham is about 5 miles east of Witney, in Oxfordshire. We send applicators to Eynsham for mastic joints. Eynsham is one of 423 places we cover in Oxfordshire. There’s a separate page for Oxford, roughly 7 miles from Eynsham.

Signs you need mastic sealing in Eynsham
Occasionally the substrate fails, not the sealant, such as crumbling render, brick arrises or frame edges. If the edges are unsound, we say so before quoting the sealing.
Things that typically lead to an enquiry:
- The same joint failures repeated across a portfolio
- Damp patches beside frames
- Failed external movement joints
- Repeated reactive repairs to the same buildings
Landlords with units on estates such as Oasis Business Park, 0.5 miles south of Eynsham, can bring frame, door and external mastic across several units into one programme.
Before you book anyone
- Whether old or failed sealant will be cut out, not overlaid
- Proof of insurance
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- The terms of the workmanship guarantee
Different surfaces, different methods
Communal areas
Entrance doors, screens and corridor junctions in communal areas all have sealant joints. Fresh joints make shared areas look looked after.
External movement joints
External movement joints take up expansion and contraction. Failed sealant in a movement joint lets water in.
For managing agents and facilities managers
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. Keys, access and contacts can be agreed in advance.
When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.
What sets the cost
The price varies from site to site. Expect it to depend on:
- Induction, permit and paperwork requirements
- The total length or number of joints
- Joint width, depth and condition
- The product specified
A quote for mastic joints depends on how many there are, their condition and the access, plus any specification you’re working to. Call for a quote.
Before you send an enquiry
A few photos plus some basic facts will normally do. It helps to include:
- Drawings or a marked-up plan, if available
- The postcode of the building
- The type of building and who uses it
- Clear photos of the problem areas
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
