What else we do in Plastow Green
Building and refurbishing in Plastow Green
Plastow Green is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack. Plastow Green lies roughly 50 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme.
New wings at hospitals like West Berkshire Community Hospital, 4.4 miles to the north-west of Plastow Green, bring long runs of window and panel joints to seal. Projects at schools like Cheam School work to term dates, so mastic is programmed tightly.
Plastow Green is about 4 miles south of Thatcham, in Hampshire. Any commercial site in Plastow Green is covered. We work across 723 places in Hampshire, from busy centres to rural villages. Reading is covered too, some 13 miles away.

Around Plastow Green
Plastow Green’s nearest station is Thatcham station, roughly 2.9 miles north of the centre. Other landmarks nearby include Old Chapel Textile Centre (2.4 miles north-west) and West Berkshire Community Hospital (4.4 miles north-west). For a walk, there’s Thatcham Reed Beds and Ladle Hill.
Aftercare for building managers
Regular inspection catches problems early. Specifically:
- Stick to the specified sealant rather than a generic substitute
- Release areas for mastic once other trades have finished in them
- Brief following trades on areas that have been sealed
- Allow flexibility for external sealing in damp or cold weather
After we’ve sealed an area, it helps to keep other trades from damaging the joints. New beads should be left to cure before cleaning or decorating nearby, and that time depends on the product, temperature and joint depth.
Sanitary joints that fail early become defects soon after occupation. Water gets behind trays, vanity tops and panels, and the repair falls into the defects period. Getting the product and preparation right first time avoids that.
Should maintenance staff do it?
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.
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
What affects the price in Plastow Green
Each job is priced on its own details. The main factors are:
- Phasing around occupants
- Specialist products, such as fire-rated or hygienic sealants
- The size and state of each joint
- Induction, permit and paperwork requirements
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.
Before you send an enquiry
For an accurate fixed quote, we need a clear picture of the site. Send us:
- Clear photographs of the problem areas
- Rough lengths or quantities, or drawings if you have them
- Access details, including height
- Your programme or deadline
Need a figure for a tender or a budget? We will quote against your scope and drawings that you can work with. If you have questions first, call the office on 01277 525 020 or use the quote form.
Common problems we fix in Plastow Green
Dust is the enemy of adhesion on a construction site. Dust, film adhesive, damp and grease on the joint faces prevent a proper bond.
It’s worth sending us details if you spot any of the following:
- Window and door perimeters that won’t pass inspection
- Cracks opening in caulked internal joints
- Old sealant on a refurbishment that needs stripping before new work
- A mastic package split between trades with no clear owner
Units on estates such as Scion Business Park, 2.2 miles east of Plastow Green, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
What your quote should include
- Health and safety accreditation such as CHAS
- How joint depth will be controlled
- Whether their applicators hold CSCS cards
- How the existing material will be dealt with
Plastow Green: questions and answers
Is a smaller place like Plastow Green outside your area?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Does your area include sites such as Scion Business Park, near Plastow Green?
Yes. Our area takes in Plastow Green and its surroundings, with estates and business parks such as Scion Business Park included. To start, just call 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
What joints do you seal on a new build?
Inside and out: frame perimeters, movement joints, caulk where called for, sanitary and kitchens.
How do I request a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.
What happens if old sealant might contain asbestos?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
When can you be on site?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
What we can’t put right
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Deciding which fire-stopping product a penetration needs
- Joints damaged after sign-off by following trades
- Designing joint widths or choosing the specification (that sits with the designer)
If you’re not sure, just call the office on 01277 525 020 or email the details over and we’ll give you a straight answer before you book.

- Floor and skirting junctions
- Cladding and panel joints
