Photos, a specification or a quick description of the joints is enough to start a fixed quote.
From enquiry to sign-off
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For a building around Culham, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.
- 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.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.

Advice
Mastic sealing in Culham
Different joints need different sealants. Window perimeters and external joints often take a low-modulus neutral-cure silicone, and MS polymer sealants stick well to many substrates and often take paint, and colours are confirmed for whichever product is used. We work on shopfronts below residential blocks, communal kitchens and washrooms and balcony and threshold joints, and the failures we are asked to look at most are no planned programme for sealant and open joints in brickwork or panels. Searching for sealant specialists in Culham? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
Around smaller places like Culham, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

What sealant work can’t fix
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Leaks from above rather than through a joint
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
- Failed window or door frames, which need a window contractor
If you’re not sure, just call 01277 525 020 or email us and we will give you a straight answer before you book.
Surfaces we seal
- Shopfronts below residential blocks
- Balcony and threshold joints
- Communal kitchens and washrooms
- External wall and movement joints
- Window and door perimeters on blocks
- Communal entrances and stairwells
Why it’s worth doing now in Culham
Resealing ahead of leaks keeps it to a maintenance task. After water has got in, there may be damp, damaged plaster or decoration to put right too, and the complaints come with it. For buildings around smaller places like Culham, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

Mastic sealing in Culham: the local picture
At about 51 miles from central London, Culham is within reach of the capital. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres. Culham is in the South East, one of the UK’s drier regions. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building normally need attention first.
Buildings close to stations like Culham station, 1.2 miles to the east of Culham, are often flats over shops, with frame mastic to keep sound. Property owners at sites such as Abingdon Science Park, 1.3 miles north of Culham, can have mastic renewed between lettings. If your remit includes a building such as Culham Parochial Church of England Primary School, frame and door mastic can be programmed for the holidays.
Culham is about 2 miles south-east of Abingdon-on-Thames, in Oxfordshire. Our applicators travel to Culham for work on mastic joints, handled exactly as we handle every other area. Culham is one of 423 places we cover in Oxfordshire. For work in that direction, see our Oxford page.

Your questions answered
Is a smaller place like Culham outside your area?
Not at all. Culham is within our area. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Can you quote for a block close to Culham station?
Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.
Is asbestos a concern with old mastic?
We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Can you send RAMS and CSCS details before starting?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member.
How long will the new sealant last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.
After the work
Regular inspection catches problems early. In particular:
- Share the asbestos register when you send details
- Look at the sunniest and most exposed elevations first
- Mention RAMS, insurance or CSCS requirements up front
- Keep bins and bikes away from communal door frames
Include sealant in planned building inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away, and note the building and elevation.
Water getting in round frames can damage plaster, decoration and the frames themselves. Resealing early keeps the job small.
