Mastic sealing in Newbury, done properly
In buildings from before 2000, some old mastics contain asbestos. Before we disturb it, we ask to see the asbestos register or survey and if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. Most enquiries involve cracked, hardened mastic round windows on a block and a mix of products and colours from past repairs, across communal kitchens and washrooms, communal entrances and stairwells and window and door perimeters on blocks. A single leaking joint is often how a building in Newbury first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
In a town such as Newbury, buildings managed by agents and landlords range from flats over shops to small blocks and offices. Mastic around frames, external joints and communal doors ages and needs renewing.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Looking after the joints
To get the most from the new sealant:
- Look at the sunniest and most exposed elevations first
- Reduce knocks to communal area joints
- Log resealing dates block by block
- Include mastic in your cyclical inspections
Ask residents or tenants to report draughts or leaks round windows early. Early reports catch failures before damage spreads.
Water getting in round frames can damage plaster, decoration and the frames themselves. Resealing early keeps the job small.
When something else is needed
Some faults sit outside our scope, and we say so rather than covering them up:
- Substrate edges that need repairing first
- Asbestos-containing sealant, which we don’t remove
- Water coming in from the roof or rainwater goods
Not sure which it is? You can call 01277 525 020 or email drawings and photos and we’ll tell you honestly.

What else we do in Newbury
Different surfaces, different methods
Window and door perimeters on blocks
Perimeter joints on blocks are best done elevation by elevation or block by block. How each joint is reached is agreed at quote stage.
Communal areas
Communal entrances, stairwells and corridors have joints at door frames, screens, skirting and floor edges. Fresh joints make shared areas look looked after.
Diagnose, treat, sign off
Occupied buildings need a little choreography. 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. Most work in Newbury is one building at a time: a school, a unit, an office or a block. Your photos, drawings or a site visit come first, followed by a fixed quote.
- Each block or building is walked and the failed joints recorded with the likely cause.
- 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.
- 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.
- Finished joints are looked over and the 12-month guarantee confirmed.
Getting the site ready
- Move anything stored against the joints
- Let us know about inductions and permits
- Have the specification and drawings to hand

Questions we’re asked in Newbury
Do you cover business parks and estates near Newbury, such as Parkway Shopping Centre?
Yes, sites like Parkway Shopping Centre are within our area, along with the rest of Newbury. 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.
Do you take on block-wide or estate-wide mastic work in Newbury?
Yes. Portfolio-wide programmes are a regular request. Send the addresses and photos and we’ll give a fixed quote.
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.
How long does a typical visit take?
It depends on the scope, but the work typically takes a day or two for a single block, longer for an estate programme. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Which sealant will you use?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Is asbestos a concern with old mastic?
In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.
Can you seal joints high up on a block?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned and we’ll confirm the approach in the quote.
Work for main contractors and building owners
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.
Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
Planned mastic for Newbury portfolios
Rainfall across the South East, Newbury included, is lower than in many parts of the UK. External mastic still waits for dry faces and the right temperature, while the elevations that take the most sun tend to show hardened mastic first. Newbury is about 53 miles from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres, and window and balcony mastic on them tends to age at the same rate.
With historic buildings such as Shaw House, 1 mile north of Newbury, in the wider area, owners of older properties around Newbury should expect mastic to need a product that suits old masonry. Older community buildings, St Nicolas Church among them, often have frames of mixed ages whose mastic varies.
Newbury is about 15 miles west of Reading, in West Berkshire. Our applicators travel to Newbury for work on mastic joints. Our West Berkshire coverage takes in 140 places, from busy centres to rural villages. For work in that direction, see our Reading page, about 15 miles away.
Business premises anywhere in RG14, RG19, RG18 and RG20 are within our area. Among the streets we cover are Market Street, London Road and Donnington Square, and sites on any of them can send details for a fixed quote.

If your building is just outside Newbury, we cover Greenham (1 mile south-east), Sandleford (1 mile south), Skinners Green (2 miles south-west), Wash Common (2 miles south-west) and Enborne (2 miles west). Bigger towns within reach include Thatcham (3 miles east), Burghfield Common (11 miles east), Hungerford (8 miles west), Fords Farm (13 miles east), Little Heath (12 miles east) and Calcot (12 miles east). As one of the bigger centres in West Berkshire, Newbury has a broad mix of commercial, public and industrial buildings.

What we’re called out for in Newbury
Communal entrances and corridors see a lot of wear, and low-level joints get damaged. Cleaning products add to the wear.
What tends to prompt an enquiry:
- Draught complaints from residents or tenants
- Failed external movement joints
- Estate-wide sealant that is simply worn out
- Communal area joints that look neglected
If you look after a block within reach of Newbury station, less than half a mile south-east of Newbury, frame and balcony mastic can be renewed on one programme.
