About our construction mastic in Sonning Common
On refurbishments, the mastic package normally includes cutting out old sealant as well as sealing new work. Old beads come out completely, as fresh silicone can’t grip old and the asbestos survey is checked first on older stock. New and existing joints then get the same preparation. Most enquiries involve existing joints on a refurb that need cutting out and resealing and caulk cracking where joints are moving more than expected, across internal decorators’ caulk, brick and block movement joints and sanitary and kitchen joints. Facilities teams, main contractors and managing agents in Sonning Common tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Building work in places the size of Sonning Common is usually small-scale: a handful of new houses, barn conversions, a school or hall extension. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

After the work
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Flag uneven or tapered frame gaps early
- Share drawings and the specification as soon as possible
- Note which sealant went where at handover
- Don’t force external sealing on a damp or frosty day
At handover, keep the product details with the O&M information. Future maintenance is easier when the products are known, and tells you what to reseal with. Tell us what records you need and we’ll confirm with the quote.
External joints sealed in poor weather are a common cause of early failure. Waiting for a dry joint and the right temperature is better than redoing work.
Construction mastic around Sonning Common: how the place shapes the job
At about 38 miles from central London, Sonning Common is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes. Sonning Common sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager.
For contractors on a campus like University of Reading, which lies south-east of Sonning Common, facade and perimeter sealing has to fit around students and term dates. Older buildings in the area around Sonning Common, such as Greys Court, 2.2 miles to the north-east of Sonning Common, need care when sealed: the product has to suit soft or historic materials. School extensions, at buildings such as Sonning Common Primary School, typically run to the summer holidays, mastic included.
Sonning Common is about 3 miles north of Caversham, in Oxfordshire. Our applicators travel to Sonning Common for work on mastic packages, handled exactly as we handle every other area. Across Oxfordshire, 423 places are covered, Sonning Common among them.

When it isn’t the sealant
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Designing joint widths or choosing the specification (that sits with the designer)
- Faulty frames rather than failed sealant
- Oversized gaps that need packing or adjustment by others
If in doubt, speak to us on 01277 525 020 or email the details over and we’ll say what we think before you book.
Where we work in Sonning Common
- Brick and block movement joints
- Internal decorators’ caulk
- Window and door perimeters
- Cladding and panel joints
- Floor and skirting junctions
- Sanitary and kitchen joints
How the job changes by surface
Internal decorators’ caulk
Caulk is easy to apply badly. A neat, consistent caulk line makes the decorators’ job quicker and keeps the snag list down.
Window and door perimeters
A frame gap that’s too wide can’t just be filled with sealant. We check them during the first walk-round and flag any that need packing or adjusting before sealing starts.
What affects the price in Sonning Common
Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:
- Specialist products, such as fire-rated or hygienic sealants
- Working within restricted access windows
- Distance, for remote addresses
- Access and working height
The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site requirements come into it too.
What we need to price the job
To price the job accurately, we need to understand the site. Useful things to include:
- The site address and postcode
- How the joints are reached, and at what height
- Specification clauses that apply
- The asbestos register, for older buildings

Questions we are asked in Sonning Common
Is Sonning Common too small for you to travel to?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Do you take on work at healthcare sites like Battle Hospital?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
How much does the work cost?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.
How long will the new sealant last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Do you guarantee new-build sealant work?
Each package is signed off with a 12-month workmanship guarantee. The guarantee covers our work, not later damage by other trades.
Can you come in just for snagging?
Yes. Snag-only work is something we take on.
Doing it in-house
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 where general trades tend to cut corners.
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
