About our construction mastic in Walton-on-Thames
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, and on older buildings we ask for the asbestos survey before disturbing anything. New and existing joints then get the same preparation. We work on cladding and panel joints, internal decorators’ caulk and brick and block movement joints, and what we are called in for most is external joints sealed in damp or cold conditions that are now failing and caulk cracking where joints are moving more than expected. Looking for mastic applicators who cover Walton-on-Thames? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Construction in a town such as Walton-on-Thames is often smaller schemes: a few new flats, a school extension, a refurbished unit. A mastic package on a smaller site still needs the same care at window perimeters and facade joints.
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.

What sealant work can’t fix
Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:
- Frames fitted out of tolerance
- Rework caused by others damaging completed areas
- Designing joint widths or choosing the specification (that sits with the designer)
If in doubt, give us a call on 01277 525 020 or email the details over and we will say what we think.

Keeping the joints sound
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Brief following trades on areas that have been sealed
- Record the products used in the O&M file
- Ask installers to correct oversized gaps first
- Don’t force external sealing on a damp or frosty day
Our 12-month guarantee covers the workmanship from sign-off. Damage by others isn’t a workmanship fault which is why protection after sealing matters.
A missed perimeter seal on one window can wet the reveal and the plaster inside. That usually means redoing finishes in a completed area. Checking perimeters before internal finishes go on avoids it.
General trades versus a specialist
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
What happens if it’s left?
On a refurbishment, there’s a choice between resealing existing frames and replacing them. If the frame is in good order, cutting out and resealing the perimeter can be all it needs. We’ll say so if a frame itself is the problem. In a town like Walton-on-Thames, a split, stained or mouldy joint is often the first thing visitors notice. Fresh sealant makes a building look maintained.
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.

Construction mastic around Walton-on-Thames: what changes locally
There are a good number of hotels within about 2 miles of Walton-on-Thames. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight. Rainfall across the South East, Walton-on-Thames included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, which is why external dates are agreed with the site manager.
Hotel extensions and refits, at places such as Oatlands Chaser Hotel, 1.1 miles south-west of Walton-on-Thames, usually run between busy periods, so the sealing is squeezed into short windows. For contractors refurbishing units at places like North Weylands Industrial Estate (1 mile east of Walton-on-Thames), the mastic covers cladding panels, roller-door and window perimeters. University estates such as Kingston University Penrhyn Road Campus (to the east of Walton-on-Thames) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.

Different surfaces, different methods
Internal decorators’ caulk
Acrylic caulk fills internal gaps around trims, boards and frames ahead of decorating. It’s paintable and suits gaps that don’t move, and we use a flexible sealant where there’s movement.
Window and door perimeters
A frame gap that’s too wide can’t just be filled with sealant. Gaps outside the product’s range are raised with the site team.
