How a job runs
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. For work around Lower Brailes, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- First we look at the mastic on each building and note what needs replacing.
- 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 where the joint and the product need them, then new sealant is applied and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.

Mastic sealing in Lower Brailes, done properly
Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Every applicator holds a CSCS card, and the work is backed by public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. We work on balcony and threshold joints, external wall and movement joints and window and door perimeters on blocks, and the failures we’re asked to look at most are damaged joints in communal entrances and corridors and the same joint failures repeated across a portfolio. Whether you call it commercial sealant work, mastic application or joint sealing, in Lower Brailes it comes down to the same thing: the right product in a properly prepared joint.
For buildings around smaller places like Lower Brailes, we group work so one trip covers it. Send photos of the frames and joints and we’ll give a fixed quote.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Aftercare for building managers
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Prioritise elevations facing the weather
- Make it easy for occupiers to report draughts
- Protect low-level joints in entrances
- List the paperwork your organisation requires when you send details
Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.
Leaks at window perimeters spoil finishes and can affect frames. Resealing early keeps the job small.
Frames, entrances and external joints in Lower Brailes
The South East is one of the drier parts of the UK. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.
If your remit includes a building such as Brailes CofE Primary School, frame and door mastic can be programmed for the holidays. Property owners at sites such as Brailes Industrial Estate (to the east of Lower Brailes) can have mastic renewed between lettings.
Lower Brailes is about 8 miles west of Banbury, in Oxfordshire. We cover commercial sites throughout Lower Brailes, whether it’s a single job or part of a planned programme. We work across 423 places in Oxfordshire, large and small. Our Oxford page has more on work in that area, about 25 miles away.

What sets the cost
Your fixed quote is built from the real scope. It takes account of:
- Backing rod, priming and other preparation
- Specialist products, such as fire-rated or hygienic sealants
- How accessible the joints are
- Whether old sealant has to be cut out first
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.
What we need to price the job
A good diagnosis starts with the right details. Let us know:
- Any dates the work must fit around
- Clear photographs of the problem areas
- Anything awkward about access or site hours
- Asbestos survey details if the building is older
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.
When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:
- Failed window or door frames, which need a window contractor
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
- Materials that need asbestos testing before work
If in doubt, give us a call on 01277 525 020 or use the quote form and we’ll say what we think before you book.
Joints and surfaces we work on
- Shopfronts below residential blocks
- External wall and movement joints
- Communal entrances and stairwells
- Communal kitchens and washrooms
- Balcony and threshold joints
- Window and door perimeters on blocks
What happens if it’s left?
Leaving failed external joints lets water reach the structure behind. Damp patches, stained plaster and decorating claims can follow, which is harder to deal with than resealing. Halls, stores and units around places like Lower Brailes may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
What you get with us
- One number for every site we cover
- CSCS-carded applicators
- 12-month guarantee on workmanship

Questions we are asked in Lower Brailes
Can you quote for mastic across several buildings in and around Lower Brailes?
Yes. Portfolio-wide programmes are a regular request. Send the addresses and photographs and we will give a fixed quote.
Is Lower Brailes off your patch?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
How many days will you need on site?
It depends on the scope, but the work usually takes one or more days per building, depending on the joint lengths and the access. For bigger or phased jobs, we will set out a timescale with the quote.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
What about access for upper-floor joints?
Every block is different. We agree access with you at quote stage so the fixed quote reflects it.
Does the weather affect the work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Common problems we fix in Lower Brailes
Many failed joints were sealed without backing rod so the mastic is bonded on three sides. It can’t stretch properly and splits as the building moves.
These are often picked up first by site or facilities staff:
- Worn sealant at communal door frames
- Leaks at window and door perimeters
- Mastic failing across several blocks on an estate
- Draughts at frames across a block
Older community buildings, Church of St George among them, often have frames of mixed ages whose mastic varies.
What to look for in a quote

- Do they follow the manufacturer’s priming guidance?
- Are they CHAS accredited or on Constructionline?
