About our mastic sealing in Owlswick
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. If you have a mix of products and colours from past repairs and occupiers reporting cold air round windows, we can put it right, on shopfronts below residential blocks, external wall and movement joints and balcony and threshold joints alike. A specialist sealant contractor works differently from a general builder: in Owlswick, that means joint design, primers and backing rod as standard.
In and around smaller places like Owlswick, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

Questions we are asked in Owlswick
Is Owlswick too small for you to travel to?
Not at all. Owlswick 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.
Will you price a mastic programme across our Owlswick portfolio?
Yes, we quote for single buildings and for programmes across several blocks. Residents are given notice through you, and the work moves building by building.
Who decides which product is used?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
How many days will you need on site?
The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.
When is resealing likely to be due?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
How do you reach windows on upper floors?
We talk through access for each building when we quote. Tell us the building height and any access already in place and we will confirm the approach in the quote.
Does weather matter for sealant 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.
After the work
Your facilities or cleaning team can help the joints last. Share these points with them:
- Protect low-level joints in entrances
- Include mastic in your cyclical inspections
- Look at the sunniest and most exposed elevations first
- Track which buildings were done and when
Include sealant in planned building inspections. Check for splits, open joints, brittle mastic and lifting edges and record where they are.
Water getting in round frames can damage plaster, decoration and the frames themselves. Resealing early keeps the job small.

Advice
What we are called out for in Owlswick
Topping up old mastic is a common shortcut. New sealant won’t grip failed sealant and the repair soon fails.
Any of the following is a good reason to get the joints checked over:
- Window mastic that has split and shrunk
- Estate-wide sealant that is simply worn out
- Occupiers reporting cold air round windows
- Patchy repairs in mismatched sealant
For a school such as Longwick Church of England Combined School, perimeter mastic on windows and doors is a holiday job.
Comparing quotes
- What the guarantee covers, and for how long
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- The named product and why it was chosen
- How the existing material will be dealt with
What sets the cost
A fixed quote reflects the actual work. It allows for:
- Whether old sealant has to be cut out first
- Specialist products, such as fire-rated or hygienic sealants
- The total length or number of joints
- Location, for remote and island sites
A quote for mastic joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.
Details that help us quote
For an accurate fixed quote, we need a clear picture of the site. Send us:
- The site address and postcode
- When you need the work done
- The product your specification calls for
- What the building is and how it’s used
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.
For owners and agents in Owlswick
Owlswick lies roughly 37 miles out from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres. Owlswick sits in one of the drier corners of the country, the South East. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.
If you look after a block within reach of Monks Risborough station, 1.5 miles south-east of Owlswick, frame and balcony mastic can be renewed on one programme. If you’re responsible for a building such as Owlswick Chapel, frame and door mastic needs the same attention as any other property.
Owlswick is about 5 miles east of Thame, in Buckinghamshire. Any commercial site in Owlswick is covered. Owlswick is one of 308 places in Buckinghamshire on our list for mastic joints. We also cover Oxford, around 16 miles from Owlswick.

Should maintenance staff do it?
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Why it’s worth doing now in Owlswick
Sealing over failed mastic looks tidy for a while. It won’t grip the old sealant and soon comes away. Cutting out and resealing properly does it once. Around Owlswick, it’s better to renew all the failing joints at once. Send photographs of each area and we will quote for the lot.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
