About our expansion joint sealing in Caversham
The seal is what lets a movement joint do its job. Once it fails, water, grit and debris get in; the joint jams, its edges take the load and the arrises spall. Resealing at the first signs of failure is far cheaper than repairing the material either side. If you have rain penetration at brick or block movement joints and hardened, cracked sealant on exposed facades, we can help, on blockwork control joints, car park decks and ramps and podiums and floor movement joints alike. Searching for sealant specialists in Caversham? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
In Caversham, as in most towns, brickwork and panel movement joints on public and commercial buildings age quietly. Once the sealant hardens or splits, water gets into the wall and the joint no longer works.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

On site: what to expect
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before we move to the next. Parking and loading for town-centre jobs in Caversham are worth mentioning when you send details. On estates and business parks it’s normally simpler.
- We assess the joints on site or from photographs, noting widths and how each has failed.
- You receive a fixed quote stating the product and the movement it is rated for.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Getting the site ready
- Let building users know which areas are affected
- Share the asbestos register for older buildings

Different surfaces, different methods
Brickwork and blockwork joints
A brick movement joint full of old mortar or debris can’t close. Everything is raked out before backing and sealant go in, and tell you if the joint looks too narrow for the movement.
Concrete and precast panel joints
Precast and concrete panel joints move daily. We use a sealant classed for the movement, laid over backing to depth.

- The site’s rules and procedures

When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It won’t put right:
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Joints too narrow for the movement, which need redesigning by the engineer
- Waterproofing layers buried beneath the sealant
If you are not sure, just ring 01277 525 020 or email us and we will give you a straight answer before you book.

Site staff or a sealant specialist?
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
Questions about Caversham
Does your area include sites such as The Station Shopping Park, near Caversham?
Yes, sites like The Station Shopping Park are within our area, along with the rest of Caversham. Send details of the unit and the work through our quote form for a quick quote.
Do we have to stop operations in Caversham while the joints are sealed?
Normally not: we work in sections and hand each one back once it has cured. The phasing plan comes with the quote.
Can one quote cover more than one building?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
What exactly is a movement joint?
Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Expansion joint is a name often used for the same thing, and either way it needs a sound seal.
Why has the sealant in our expansion joints split?
Usually the joint is moving more than the sealant can take. That’s why we check width, depth and movement class before quoting.
Which sealant will you use?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
