Frames, entrances and external joints in Hempton
At about 63 miles from central London, Hempton is within reach of the capital. 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. Rainfall across the South East, Hempton included, is lower than in many parts of the UK. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building typically need attention first.
If you’re responsible for a building such as Saint John the Evangelist, frame and door mastic needs the same attention as any other property. Historic properties like Broughton Castle, 4.3 miles north-west of Hempton, show the age of some local stock, where frame mastic must suit soft brick or stone. Buildings close to stations like Kings Sutton station (to the north-east of Hempton) are often flats over shops, with frame mastic to keep sound.
Hempton is about 6 miles south of Banbury, in Oxfordshire. We cover Hempton and the rest of Oxfordshire, with the same fixed quotes and 12-month guarantee as everywhere else. Hempton is one of 423 places in Oxfordshire on our list. Oxford is covered too, around 17 miles from Hempton.

Mastic sealing in Hempton, done properly
Blocks are lived in, so access and disruption have to be thought through. The sequence, the areas and the dates are settled with you, giving you what you need to notify residents. Communal entrances and stairs stay usable while we work. We work on communal kitchens and washrooms, shopfronts below residential blocks and external wall and movement joints, and the failures we are asked to look at most are water getting in round frames after rain and old repairs sealed over failed mastic. A single leaking joint is often how a building in Hempton first comes to us: we look at the rest while we’re there and tell you what we find.
For owners with a single building near Hempton, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Owners, agents and contractors
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.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Questions we are asked in Hempton
Is Hempton too far out for you?
No. Small places get the same service as large ones. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Can you quote for a block close to Kings Sutton station?
Yes, and several blocks can go on one quote. Photos of each elevation help us quote accurately.
Who decides which product is used?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
How long does a job like this take?
The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.
Can you seal joints high up on a block?
Every block is different. We agree access with you at quote stage so there are no surprises.
Do you work with property factors and landlords?
Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.
What guarantee do you give on resealing?
A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.
From enquiry to sign-off

What sets the cost
These are the things that shape the price:
- How much there is to seal
- Access and working height
- Which sealant the job calls for
- Whether the work must be split into stages
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.
Details that help us quote
For an accurate fixed quote, we need to understand the site. Useful things to include:
- Any specification or named product
- How the joints are reached, and at what height
- Approximate linear metres or a joint schedule
- A wide shot and a close-up of the area
Send us photos, 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.
Keeping the joints sound
A few simple habits keep the new joints working:
- Avoid piecemeal callouts where you can
- Keep bins and bikes away from communal door frames
- Log resealing dates block by block
- Start inspections with the most exposed faces
If a joint we sealed fails within 12 months, tell us and we will look at it. After that, regular inspection keeps the programme on track.
Leaks at window perimeters spoil finishes and can affect frames. Early resealing is far simpler than repairs inside.
When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It won’t put right:
- Frames that are rotten, warped or broken
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
- Materials that need asbestos testing before work
If in doubt, speak to us on 01277 525 020 or email us and we’ll say what we think before you book.
What we seal
- Balcony and threshold joints
- Shopfronts below residential blocks
- Communal entrances and stairwells
- External wall and movement joints
- Communal kitchens and washrooms
- Window and door perimeters on blocks
What happens if it’s left?
Adding sealant to cyclical maintenance is an easy win. Waiting until leaks appear means working under pressure with less control over timing. Halls, stores and units around places like Hempton may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.
