Mastic sealing in Tetsworth
Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. A planned, building-by-building programme often works better than reacting to each complaint, with each block quoted and scheduled in turn. If you’re dealing with communal area joints that look neglected and occupiers reporting cold air round windows, we can help, on balcony and threshold joints, window and door perimeters on blocks and shopfronts below residential blocks alike. Whether you call it commercial sealant work, mastic application or joint sealing, in Tetsworth it comes down to the same thing: the right product in a properly prepared joint.
Around smaller places like Tetsworth, 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.
We stand by our work with a 12-month guarantee. That covers our preparation and application.

Quoting for work in Tetsworth
Your fixed quote is built from the real scope. It takes account of:
- The size and state of each joint
- Removal of failed or old sealant
- Specialist products, such as fire-rated or hygienic sealants
- Location, for remote and island sites
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
What to include in your enquiry
To price the job accurately, we need to understand the site. Useful things to include:
- The site address and postcode
- The asbestos register, for older buildings
- How the joints are reached, and at what height
- When you need the work done
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

For managing agents and facilities managers
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
How a job runs
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Rural sites near Tetsworth may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
- First comes a look at the joints and, for older buildings, the asbestos records.
- A fixed quote covers the joints, products and order of work.
- We strip out the old sealant.
- The joints are prepared and resealed with the right product.
- Buildings are completed in turn.
Preparing the site

When to call us in Tetsworth
We often find joints filled solid with no backing rod so the mastic is bonded on three sides. That three-sided adhesion stops it stretching and it tears.
Any of the following is a good reason to get the joints checked over:
- Water getting in round frames after rain
- Old repairs sealed over failed mastic
- Estate-wide sealant that is simply worn out
- Damaged joints in communal entrances and corridors
If you look after a block within reach of Haddenham & Thame Parkway station, 5 miles north-east of Tetsworth, frame and balcony mastic can be renewed on one programme.
What to look for in a quote
- Whether old or failed sealant will be cut out, not overlaid
- Health and safety accreditation such as CHAS
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- How they’ll work around occupants
Surface by surface
Commercial and mixed-use buildings
Landlords with commercial portfolios have shopfronts, office entrances and external joints to look after. A planned programme suits multi-building portfolios.
Estate-wide resealing programmes
An estate of similar buildings suits a rolling programme. Each block is priced and scheduled in order.
Your questions answered
Is Tetsworth too small for you to travel to?
Not at all: smaller places are covered as well as towns. 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 take on a block within reach of Haddenham & Thame Parkway station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Photos of each elevation help us quote accurately.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
What guarantee do you give on resealing?
Our workmanship carries a 12-month guarantee, backed by public liability insurance.
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 checks let you plan resealing before leaks or damage.
How many days will you need on site?
We plan the time on site around your programme and access. You’ll have an expected duration with the quote.
Can you plan resealing across several buildings?
We can. Each building is inspected, quoted and scheduled in turn starting wherever is most urgent.
What happens if it’s left?
Failed perimeter mastic lets cold air in around frames, and they often blame the windows. In many cases, new perimeter sealant deals with it when the frames themselves are sound. For buildings around smaller places like Tetsworth, water damage can go unnoticed for longer, especially where a building isn’t used daily, 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: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
What you get with us
- Coloured sealants to suit the setting, where available
- Colour agreed before work starts
- CHAS accredited
- Joints cleaned back to sound surfaces

For owners and agents in Tetsworth
Tetsworth lies roughly 42 miles out from central London. Managed blocks of flats are a big part of commuter-belt property, and window and balcony mastic on them tends to age at the same rate. Rainfall across the South East, Tetsworth included, is lower than in many parts of the UK. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first.
With historic buildings such as Adwell House, 1.4 miles south of Tetsworth, in the wider area, owners of older properties around Tetsworth should expect mastic to need a product that suits old masonry. For a school such as Tetsworth Primary School, perimeter mastic on windows and doors is a holiday job.
