Construction mastic in Charvil
Refurbishment work needs a slightly different approach from new build. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone. New and existing joints then get the same preparation. We work on floor and skirting junctions, sanitary and kitchen joints and internal decorators’ caulk, and the failures we are asked to look at most are old sealant on a refurbishment that needs stripping before new work and sanitary sealant damaged by following trades. Most enquiries from Charvil start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
In a smaller place such as Charvil, construction tends to mean small housing schemes, conversions and extensions to community buildings. Even a small site needs its perimeter and facade joints sized, backed and sealed properly.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Building and refurbishing in Charvil
Several hotels sit less than 2 miles from Charvil. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. Central London is about 34 miles from Charvil. Towns within reach of London tend to keep building, from flats to offices and schools, which keeps mastic packages in demand.
University estates such as University of Reading, 1.9 miles to the north-west of Charvil, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. Units on estates such as Loddon Vale Shopping Centre, 1.5 miles to the south of Charvil, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
Charvil is about 2 miles north of Woodley, in Wokingham. We cover Charvil and the rest of Wokingham, with the same fixed quotes and 12-month guarantee as everywhere else. Our Wokingham coverage takes in 42 places.

Landmarks near Charvil
We work on buildings around The Piggott School, Polehampton Church of England Infant School and The Wagon And Horses Public House. For rail, the closest station is Twyford station, roughly 0.9 miles east of the centre. Well-known places in the area include Royal Berkshire Hospital (3.7 miles south-west) and Berkshire Medical Heritage Centre Museum (3.6 miles south-west). The countryside around Charvil includes Sonning Hill and South Lake.
Common problems we fix in Charvil
Shrinkage and settlement in the first months put new joints under strain. Plaster, screeds, timber and blockwork all shrink as they lose moisture. Choosing the right product for each joint reduces that.
Things that usually lead to an enquiry:
- New external sealant already peeling away
- A mastic package split between trades with no clear owner
- Window and door perimeters that won’t pass inspection
- Mastic snags holding up handover
For contractors at a college like Bracknell & Wokingham College, 2.7 miles to the south-west of Charvil, perimeters and internal sealant are timed for the holidays.
Comparing quotes
- Their public liability cover
- What the guarantee covers, and for how long
- How they’ll work around occupants
- Do they follow the manufacturer’s priming guidance?
How the quote is worked out
There’s no standard rate for sealant work, because every site is different. What we take into account:
- Quantities, in metres or numbers
- Removal of failed or old sealant
- Working within restricted access windows
- Any access equipment needed
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
Sending details for a quote
The more we know, the firmer the quote. When you get in touch, include:
- Whether an asbestos survey exists
- Where the site is, with the postcode
- Drawings or a marked-up plan, if available
- The product your specification calls for

Charvil: questions and answers
Can you work around term dates at a campus such as University of Reading?
Yes, holiday working periods are the norm on campus jobs. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is a hospital such as Royal Berkshire Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can you come in just for snagging?
Yes. We can work through a mastic snag list area by area before handover.
Can you work to our specification?
Specification first, then the maker’s instructions. Primers, backing and joint depth follow what the manufacturer sets out.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Can you fit around our working hours?
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.
Can you work while the building is occupied?
In most cases, yes. Phased work can be planned so areas stay in use.

Related advice
Site staff or a sealant specialist?
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Maintenance after handover
Regular inspection catches problems early. Specifically:
- Plan external elevations with the weather in mind
- Protect sealed areas from following trades
- Ask for joint and product checks before the package is urgent
- Ask cleaners to use soft cloths around fresh sealant
Once an area is sealed, protect it from following trades. New beads should be left to cure before cleaning or decorating nearby, and that time depends on the product, temperature and joint depth.
Oversized gaps are a problem better caught early. Filling a wide gap with sealant alone sets up a failure so packing or adjustment by the installer comes first. We raise them during our first walk of the area.
