Mastic sealing for commercial buildings in Dunsden Green
Treatment starts with a proper look: which joints have failed, why, and whether sealant is the right answer. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in, with backing rod setting the depth where it’s needed. If you have a mix of products and colours from past repairs and draught complaints from residents or tenants, we can help, on communal kitchens and washrooms, balcony and threshold joints and external wall and movement joints alike. Most enquiries from Dunsden Green start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Rural conversions near places like Dunsden Green often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Your questions answered
Is Dunsden Green 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. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Will you take on work at estates like Suttons Business Park, close to Dunsden Green?
Yes. Estates, retail parks and business parks around Dunsden Green, Suttons Business Park among them, are all within reach. A few photos and the unit address let us price the work.
Do you need to see the site first?
Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit.
What do you charge?
It depends on the job: quantities, access, the product and any phasing. Call for a quote and we will price it properly.
How do you handle work on occupied blocks?
The work is planned around occupiers. We agree the programme so you can notify occupiers and communal access is kept open.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.
Honest limits
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:
- Broken glass or failed sealed units
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Masonry that has broken away beside the joint
Not sure which it is? You can call 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.

Doing it in-house
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Quoting for work in Dunsden Green
To price the job, we consider:
- How much there is to seal
- Joint width, depth and condition
- Whether old sealant has to be cut out first
- Location, for remote and island sites
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
Before you send an enquiry
The more we know, the firmer the quote. Helpful details to send:
- Where the site is, with the postcode
- Access details, including height
- When you need the work done
- Photos of the joints, close up and from further back
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, phone 01277 525 020 or email us.
Block-wide mastic in Dunsden Green
At about 36 miles from central London, Dunsden Green 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. Dunsden Green is in the South East, one of the UK’s drier regions. 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.
Trustees of buildings like All Saints Church can bring frame and external mastic into a planned maintenance list. Blocks of flats and mixed-use buildings often cluster around stations such as Reading station (2.6 miles south-west of Dunsden Green) and their window and balcony mastic tends to age at the same rate across a building. Schools and community buildings such as St Martin's Catholic Primary School need frame and external mastic kept sound like any building.
Dunsden Green is about 1 mile north-east of Caversham, in Oxfordshire. Anywhere in RG4, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Across Oxfordshire, 423 places are covered, Dunsden Green among them.
