Advice
Mastic sealing in Newtown Common
On a residential block, the work happens around people’s lives. The sequence, the areas and the dates are settled with you so you can let residents know what is happening. Communal entrances and stairs stay usable while we work. If you’re dealing with water getting in round frames after rain and movement joints with sealant missing, we can help, on shopfronts below residential blocks, window and door perimeters on blocks and communal kitchens and washrooms alike. Most enquiries from Newtown Common 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 Newtown Common often set modern frames into older stone, flint or brick. The mastic needs to suit an irregular masonry face and the look of the building.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Questions we’re asked in Newtown Common
Will you take on work at estates like Newbury Retail Park, close to Newtown Common?
Yes, sites like Newbury Retail Park are within our area, along with the rest of Newtown Common. To start, just give us a call on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Is Newtown Common too small for you to travel to?
No. Places such as Newtown Common are covered as much as the big towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Do you seal on top of existing sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
How do we ask for a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.
Can you plan resealing across several buildings?
Block-wide and estate programmes are common. The quote can be split however suits your budgeting.
Will you come and look before quoting?
That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.
What do you charge?
There isn’t a price list, because every site is different. Send photographs or drawings and we will price it at a fixed figure.
When something else is needed
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Leaks through the frame itself rather than the perimeter
- Substrate edges that need repairing first
If you are not sure, just call the office on 01277 525 020 or email drawings and photos and we’ll give you a straight answer.

What else we do in Newtown Common
Looking after the joints
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Plan resealing building by building rather than complaint by complaint
- Include mastic in your cyclical inspections
- Keep bins and bikes away from communal door frames
- Have the asbestos survey to hand for older buildings
If paintable sealant was used, decoration can follow once it has cured. Silicone typically can’t be painted, so keep decorators off it unless told otherwise.
The longer failed joints are left, the more likely the substrate edges break up. Then the edges may need repairing first and the job grows.
How the job changes by surface
Communal areas
Communal entrances, stairwells and corridors have joints at door frames, screens, skirting and floor edges. Tidy, sound joints keep them looking cared for.
Planned maintenance
Resealing can be scheduled alongside other planned works, building by building.
Site staff or a sealant specialist?
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
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.
Blocks and managed buildings in Newtown Common
Newtown Common lies roughly 54 miles out from central London. Managed blocks of flats are a big part of commuter-belt property; their frame mastic often ages block-wide. Rainfall across the South East, Newtown Common included, is lower than in many parts of the UK. Outside work still depends on dry joints, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first.
Older community buildings, Church of St Mary and St John the Baptist among them, often have frames of mixed ages whose mastic varies. With historic buildings such as Highclere Castle, 3.1 miles to the south-west of Newtown Common, in the wider area, owners of older properties around Newtown Common should expect mastic to need a product that suits old masonry. Blocks of flats and mixed-use buildings often cluster around stations such as Newbury station, 2.2 miles north of Newtown Common, and their window and balcony mastic tends to age at the same rate across a building.

Why it’s worth doing now in Newtown Common
Sealing over failed mastic looks tidy for a while. It won’t grip the old sealant and soon comes away. Cutting out and resealing properly does it once.
