About our mastic sealing in Newtown
On a residential block, the work happens around people’s lives. The sequence, the areas and the dates are settled with you, giving you what you need to notify residents. Communal entrances and stairs stay usable throughout. Site teams most often ask us about the same joint failures repeated across a portfolio and old repairs sealed over failed mastic, on communal kitchens and washrooms, external wall and movement joints and shopfronts below residential blocks. Most enquiries from Newtown 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.
Around smaller places like Newtown, 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.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

How a job runs
Occupied buildings need a little choreography. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. Jobs in and around smaller places like Newtown are typically planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- We check the asbestos register for older buildings and look at the joints.
- The products and programme are set out in a fixed quote.
- We strip out the old sealant.
- The joints are prepared and resealed with the right product.
- Buildings are completed in turn.
Getting the site ready
- Explain the parking and delivery arrangements
- Tell staff and tenants when we will be in
- Have the specification and drawings to hand
Ask for a quote
A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or give us a call on 01277 525 020 or email drawings and photos if you’d rather talk the job through.

- Roof leaks, gutters or failed flashings that aren’t sealant joints
If in doubt, call the office on 01277 525 020 or send photos by email and we will say what we think before you book.

Do you need mastic sealing in Newtown?
Many failed joints were sealed without backing rod, so the mastic is glued to the joint bottom too. It can’t stretch properly and splits as the building moves.
Look out for the following:
- Damp patches beside frames
- Draught complaints from residents or tenants
- Brittle perimeter mastic across a building
- Complaints coming in block by block
Churches, halls and community buildings such as Holy Spirit Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Blocks and managed buildings in Newtown
Newtown lies within about 1 mile of the sea. On buildings near the shore, the side facing the weather normally needs its mastic renewed first; plan inspections around that. Rainfall across the South East, Newtown included, is lower than in many parts of the UK. Outside work still depends on dry joints, and the sunniest, most exposed sides of a building usually need attention first.
Older buildings near Newtown, from historic houses such as Swainston Manor, 1.6 miles south-east of Newtown, to more modest stock, need compatible products when frames are resealed. For owners of several units at places like Porchfield Business Park, under half a mile to the east of Newtown, one programme can deal with frame and external mastic across the lot.
Newtown is about 4 miles west of Newport, in the Isle of Wight. Commercial clients in Newtown use us for work on mastic joints, as part of our coverage of the Isle of Wight. Our the Isle of Wight coverage takes in 125 places. Southampton is covered too, around 14 miles from Newtown.
Work on mastic joints is covered throughout PO30, whatever the building. Just outside Newtown, we also work in Locksgreen (1 mile east), Porchfield (1 mile north-east), Great Thorness (2 miles north-east), Forest Side (3 miles east) and Rew Street (4 miles north-east). Bigger towns within reach include Newport (4 miles east), Ryde (10 miles east), Cowes (5 miles north-east), Sandown (11 miles east), Shanklin (11 miles south-east) and Ventnor (11 miles south-east). Remote and island addresses take more planning, from travel and ferries to the weather, so mention the location when you speak to us on 01277 525 020 or email drawings and photos.

Questions about Newtown
Does a coastal location like Newtown affect which sealant is used?
It can. Coastal exposure works external joints harder than inland weather. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Is a smaller place like Newtown outside your area?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
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 checks let you plan resealing before leaks or damage.
Can you reseal a whole block or estate?
Yes, planned programmes suit estates and portfolios. You get a fixed quote per building or for the whole job.
Can you take on resealing for a block portfolio?
Yes, that’s exactly who this service is for. Buildings are scheduled in turn with dates agreed in advance.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Do you supply RAMS and insurance details?
We’re CHAS accredited, a Constructionline member and carry public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
After the work
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Make mastic part of routine maintenance checks
- Prioritise elevations facing the weather
- Make it easy for occupiers to report draughts
- Track which buildings were done and when
Encourage occupiers to report water or draughts at frames. Early reports catch failures before damage spreads.
One failed perimeter usually means others on the same building are close so a single failure is a sign to check the rest. A planned reseal saves repeated visits.
Why it’s worth doing now in Newtown
Replacing mastic before water gets in is a planned job. Once water has tracked in, the repair list grows, and the complaints come with it. One visit to deal with every failing joint makes more sense than several trips to a place like Newtown, rather than one at a time. Send photographs of each area and we will quote for the lot.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.
