About our mastic sealing in Shaw
We diagnose before we prescribe: which joints have failed, why, and whether sealant is the right answer. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed and backing rod used wherever a joint is deep. We work on shopfronts below residential blocks, communal kitchens and washrooms and window and door perimeters on blocks, and the usual reasons a site gets in touch are occupiers reporting cold air round windows and old repairs sealed over failed mastic. A single leaking joint is often how a building in Shaw first comes to us: we look at the rest while we’re there and tell you what we find.
Converted and older buildings in and around Shaw often put modern windows into old walls. Perimeter joints need a sealant that suits both frame and masonry.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Questions about Shaw
Can you quote for a block close to Newbury Racecourse station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Is a smaller place like Shaw outside your area?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
How long will the new sealant last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Can weather delay the job?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Do you work for managing agents and housing associations?
Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.
When to call us in Shaw
Frames, panels and masonry expand and contract through the year, and every joint has to stretch and squeeze with them. If the joint or the product wasn’t suited to the movement, it splits long before it should.
Clients usually get in touch after noticing something like this:
- Open joints in brickwork or panels
- A mix of products and colours from past repairs
- Estate-wide sealant that is simply worn out
- Cracked, hardened mastic round windows on a block
Churches, halls and community buildings such as Parish Church of St Mary are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
What your quote should include
- How they handle RAMS and site documents
- Proof of insurance
- Their approach to joint depth and backing
- The named product and why it was chosen
Mastic sealing in Shaw: the local picture
Shaw is about 53 miles from central London. Managed blocks of flats are a big part of commuter-belt property. Shaw 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.
If you look after a block within reach of Newbury Racecourse station, which lies south-east of Shaw, frame and balcony mastic can be renewed on one programme. Landlords with units on estates such as Riverpark Industrial Estate, less than half a mile to the south of Shaw, can bring frame, door and external mastic across several units into one programme.
Shaw is about 1 mile north-east of Newbury, in West Berkshire. We send applicators to Shaw for mastic joints. 140 places across West Berkshire fall within our area, Shaw among them. Reading is covered too, some 15 miles away.

Quoting for work in Shaw
Each job is priced on its own details. The main factors are:
- Working within restricted access windows

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
Before you send an enquiry
There’s no need for a formal survey. A few details are enough to get going:
- Specification clauses that apply
- When you need the work done
- Whether the building will be occupied during the work
- The postcode of the building

How the job changes by surface
Estate-wide resealing programmes
A programme can start with the worst buildings and work down. You get one fixed quote per building or for the whole estate.
Tenement and older buildings
Older buildings, including Scotland’s sandstone tenements, have their own joint details. We look at the substrate before choosing a sealant.
Diagnose, treat, sign off
Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. If neighbouring businesses or buildings around Shaw need work too, visits can be combined. Mention the building’s opening times and we will work within them.
- First we look at the mastic on each building and note what needs replacing.
- A fixed quote follows, split by block or building if that suits you.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Before we start on site
- Have the specification and drawings to hand
- Share the asbestos register for older buildings
- Let building users know which areas are affected

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.
Advice
What happens if it’s left?
A bead run over old mastic can look like a repair. It doesn’t bond and normally fails within a short time. Full removal and proper preparation is what lasts. In a smaller place such as Shaw, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

General trades versus a specialist
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
