Mastic sealing in Chalkshire, done properly
Most buildings come with mastic joints nobody has looked at since handover and it slowly wears out: it sits round windows and doors, along external joints and through communal areas. Once it cracks, hardens or comes away, draughts and water find a way in, and occupiers start reporting it. We work on window and door perimeters on blocks, communal entrances and stairwells and communal kitchens and washrooms, and what we’re called in for most is estate-wide sealant that is simply worn out and cracked, hardened mastic round windows on a block. Searching for sealant specialists in Chalkshire? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Around smaller places like Chalkshire, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
Every job we finish is backed by a 12-month workmanship guarantee, in Chalkshire as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Do you work for managing agents with blocks near Little Kimble station?

How many days will you need on site?

Can you follow the specification on our project?
Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.
Is mastic sealing guaranteed?
A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
Do you check for asbestos in old sealant?
In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.
Mastic sealing around Chalkshire: what changes locally
Chalkshire sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first. At about 35 miles from central London, Chalkshire is within reach of the capital. Managed blocks of flats are a big part of commuter-belt property; their frame mastic often ages block-wide.
Older community buildings, Church of St Peter and St Paul among them, often have frames of mixed ages whose mastic varies. Property owners at sites such as Station Approach Business Park (1.3 miles east of Chalkshire) can have mastic renewed between lettings.
Chalkshire is about 4 miles south of Aylesbury, in Buckinghamshire.

Around Chalkshire
Locally, jobs take us to sites close to The Russell Arms. The nearest railway station is Little Kimble station, roughly 1.3 miles south-west. A little further out are Little Kimble Motte (1.1 miles south-west) and Stoke Mandeville Hospital (2.7 miles north). The countryside around Chalkshire includes Brush Hill Local Nature Reserve and Coombe Hill.
Should maintenance staff do it?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Leave it or put it right?
Leaving failed external joints lets water reach the structure behind. Damp patches, stained plaster and decorating claims can follow and those cost far more to put right. Around Chalkshire, it’s better to renew all the failing joints at once. Send photographs of each area and we’ll quote for the lot.
What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote when you are ready.

- Failed window or door frames, which need a window contractor
- Broken glass or failed sealed units
If in doubt, give us a call on 01277 525 020 or send photos by email and we’ll say what we think.
What we seal

Common problems we fix in Chalkshire
Many failed joints were sealed without backing rod so the mastic is bonded on three sides. That three-sided adhesion stops it stretching and it tears.
It’s worth sending us details if you spot any of the following:
- Water getting in round frames after rain
- Occupiers reporting cold air round windows
- Failed external movement joints
- Old repairs sealed over failed mastic
If you manage student housing near a university such as University Campus Aylesbury Vale, which lies north of Chalkshire, the summer turnaround is the time for mastic.

- Are they CHAS accredited or on Constructionline?
