How we handle mastic sealing in Jennett's Park
Owners and agents typically inherit a building’s mastic rather than choose it and it slowly wears out: it sits round windows and doors, along external joints and through communal areas. Once it cracks, hardens or comes away, draughts and water find a way in, and occupiers start reporting it. We work on shopfronts below residential blocks, window and door perimeters on blocks and communal entrances and stairwells, and what we are called in for most is failed external movement joints and mastic failing across several blocks on an estate. For commercial sealant work in Jennett's Park, you deal with one contact from quote to sign-off, whether it’s one building or several.
Places the size of Jennett's Park typically have some housing association stock, small blocks and mixed-use buildings. Their window perimeters and external joints need renewing as the mastic ages.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

FAQs: Jennett's Park
Will you take on work at estates like Bracknell Enterprise Centre, close to Jennett's Park?
Yes. We cover Jennett's Park and the area around it, including industrial estates, business parks and retail parks such as Bracknell Enterprise Centre. To start, just speak to us on 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Do you work for managing agents with blocks near Martins Heron station?
Yes, and several blocks can go on one quote. Send the address, photographs of the elevations and your access arrangements, and we will give a fixed quote.
How do you choose the sealant?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
What about access for upper-floor joints?
It depends on the building. How upper joints are reached is agreed before work is booked so there are no surprises.
Do you supply RAMS and insurance details?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.
Will residents or tenants be disturbed?
Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so you can arrange it with occupiers.
Do you guarantee the mastic work?
There is a 12-month guarantee on our workmanship and we hold public liability insurance.
Doing it in-house
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
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.
Block-wide mastic in Jennett's Park
Jennett's Park sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building typically need attention first. The planned town of Bracknell is on Jennett's Park’s doorstep. Estates from the same phase normally have mastic of the same age, so owners and associations can deal with it block by block.
For owners of several units at places like Bracknell Enterprise Centre (1.4 miles west of Jennett's Park), one programme can deal with frame and external mastic across the lot. Student blocks close to universities like Imperial College Silwood Park Campus, 3.6 miles to the east of Jennett's Park, are easiest to work on between tenancies.

On site: what to expect
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes anything from a day to a few weeks, depending on the number of buildings and joints, and our waste is bagged and taken away as we go. If neighbouring businesses or buildings around Jennett's Park need work too, visits can be combined. Tell us your site hours and we will plan around them.
- First comes a look at the joints and, for older buildings, the asbestos records.

How the job changes by surface
Window and door perimeters on blocks
We normally work through a block’s windows in a planned order. Access is agreed with you before the quote is fixed.
Planned maintenance
Mastic wears out like any building component; how fast comes down to movement, weather, UV and the product. Regular inspection is the best way to plan resealing.
Looking after the joints
Problems stay small when the joints are checked regularly. Specifically:
- Have the asbestos survey to hand for older buildings
- Make it easy for occupiers to report draughts
- Prioritise elevations facing the weather
- Share your contractor requirements early
Protect entrance and corridor joints from knocks where possible. Knocks cause many early failures in communal areas.
Water getting in round frames can damage plaster, decoration and the frames themselves. Resealing early keeps the job small.

When to call us in Jennett's Park
Much failed sealant was laid on dirty, dusty or damp surfaces. Without clean, sound faces and a primer where the product needs one it comes away from one face.
Site and facilities staff are often the first to spot these:
- Brittle perimeter mastic across a building
- Draught complaints from residents or tenants
- Worn sealant at communal door frames
- Failed external movement joints
Buildings close to stations like Martins Heron station, under half a mile to the east of Jennett's Park, are often flats over shops, with frame mastic to keep sound.
