Leave it or put it right?
Draughts round window perimeters cost occupiers comfort, and they often blame the windows. In many cases, new perimeter sealant deals with it where the frames themselves are sound. Around Chearsley, it’s better to renew all the failing joints at once. Send photos of each area and we’ll quote for the lot.
A quote for mastic joints depends on quantities, condition and access. Call for a quote.

Mastic sealing in Chearsley
Different joints need different sealants. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, 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 communal entrances and stairwells, window and door perimeters on blocks and external wall and movement joints, and the usual reasons a site gets in touch are failed external movement joints and no planned programme for sealant. Most enquiries from Chearsley start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
For owners with a single building near Chearsley, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Chearsley: questions and answers
Is Chearsley off your patch?
Not at all. Chearsley is within our area. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Do you work for managing agents with blocks near Haddenham & Thame Parkway station?
Yes, and several blocks can go on one quote. Send the address, photographs of the elevations and your access arrangements, and we’ll give a fixed quote.
Will residents or tenants be disturbed?
The work is planned around occupiers. Dates and areas are agreed with you so residents or tenants can be told and communal access is kept open.
Do you work for managing agents and housing associations?
Yes, block and estate work is a core part of what we do. We work through buildings in a planned order so you can plan around it.
Do you supply RAMS and insurance details?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Is asbestos a concern with old mastic?
Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.
Do you do block-wide mastic programmes?
Yes. We survey and price each building, then work through them in order starting wherever is most urgent.

What we can’t put right
We check first that sealant really is the fix. It isn’t the answer for:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Substrate edges that need repairing first
Not sure which it is? You can call the office on 01277 525 020 or email drawings and photos and we’ll tell you honestly.
What we seal
- Shopfronts below residential blocks
- Balcony and threshold joints

- Communal entrances and stairwells
- Window and door perimeters on blocks
On site: what to expect
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes anything from a day to a few weeks, depending on the number of buildings and joints, and our waste is bagged and taken away as we go. For work around Chearsley, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- We inspect the joints, building by building, and record what has failed and why.
- You get a fixed quote, priced per building where that helps your budgeting.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Before we start on site
- Confirm the product named in the specification
- Share the asbestos register for older buildings
- Let building users know which areas are affected

Advice
Signs you need mastic sealing in Chearsley
In communal areas, joints take knocks from bins, bikes, buggies and deliveries, and low-level joints get damaged. Cleaning products add to the wear.
Site and facilities staff are often the first to spot these:
- Old repairs sealed over failed mastic
- Damp patches beside frames
- Cracked, hardened mastic round windows on a block
- Communal area joints that look neglected
With historic buildings such as Waddesdon Manor, 3.7 miles north of Chearsley, in the wider area, owners of older properties around Chearsley should expect mastic to need a product that suits old masonry.
