Our commercial sealant contractors service in Reading
A reseal stands or falls on the preparation underneath it. Silicone has no grip on cured silicone, so the failed bead is cut out completely. Primer is used wherever the manufacturer calls for it on that surface and the joint depth is controlled with backing rod. Site teams most often ask us about black mould through washroom sealant that won’t clean off and damp patches where an external joint has failed, across external facade joints, washrooms and tea points and movement joints in walls and floors.
We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area.
- First, details reach us through the quote form or a site visit.
- The cause is diagnosed and the scope priced as a fixed quote.
- Where parts of the building must stay open, the work is phased.
- Old sealant is cut out completely, never sealed over.
- Each joint gets a suitable sealant, laid to depth and tooled.
- We check the work with you, and the 12-month guarantee starts.

Commercial sealant contractors across Reading: the area picture
Across Reading, from Caversham, Norcot and Tilehurst to the smaller places between, commercial buildings run from high-street shops and offices to hotels, schools and business parks. Because we cover all of it, multi-site occupiers can bring every building under one quote.
The South East has large numbers of business parks and industrial estates, especially around the motorway corridors, and Reading is part of the area we cover.
Reading: Units at retail parks like Reading Link Retail Park (less than half a mile south of Reading) change hands and get refitted, with new joints at every frontage. Shops and cafés around stations like Reading West station, 0.7 miles north-west of Reading, trade from early, so work is timed around them.
How the job changes by surface
Movement joints in walls and floors
Floor joints that take trolleys or forklifts need a tougher filler or sealant. The choice comes down to how much the joint moves and what runs over it, and tell you if the edges need repairing first.
Shop fronts and retail fit-outs
Most shops can’t close for a reseal. Tell us your trading hours and access windows and we’ll plan around them.
After the work
Problems stay small when the joints are checked regularly. In particular:
- Add sealant to the planned maintenance inspection list
- Have extract fans checked so wet areas dry out
- Keep a record of which joints were resealed and when
- Check the asbestos register before anyone disturbs old sealant in an older building
New joints need their full cure time before they take water, cleaning or traffic. That time depends on the product, the temperature and the joint depth. Keeping signs or barriers up until then protects the finish.
Each spell of wet weather pushes more water through an open joint. Behind a panel or frame, that water can sit unseen for a long time. Resealing early keeps the problem in the sealant and out of the building.
How the quote is worked out
To price the job, we consider:
- Phasing around occupants
- Travel to remote or island sites
- How much there is to seal
- Backing rod, priming and other preparation
What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a quote once you have the details.
Sending details for a quote
Diagnosis starts before we arrive. Tell us:
- Photos of the joints, close up and from further back
- Asbestos survey details if the building is older
- What the building is and how it’s used
- Approximate linear metres or a joint schedule
Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
Why it fails
Outside, sunlight and rain wear sealant down year after year. UV hardens the surface while wind and rain work at the edges; in time the surface chalks, hardens and cracks. Once it stiffens, the joint opens up at the next big temperature swing.
Most enquiries start with one or more of the following:
- Leaks that seem to come through a sealant line
- Expansion joints with the sealant torn out
- Window and door perimeter joints that have cracked open
- Weathered facade sealant that no longer flexes
Doing it in-house
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Questions about Reading
Do you work for facilities managers and managing agents?
Yes. You can send details through our quote form, and tell us what site paperwork you need.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and we’ll price the work to it.
Is it OK to apply fresh sealant over existing beads?
The old bead is stripped out first. Then the joint is cleaned, primed where the maker specifies, backed to depth and resealed.
How do we get a quote?
Photos, drawings or a schedule of the joints are typically enough to start through the quote form on this site. Where we need to see it, we’ll arrange a site visit, then send a fixed quote.
How many days will you need on site?
That varies with the scale of the job, though a typical visit usually takes part of a day on a small job and longer where several buildings or phases are involved. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Do you cover Reading?
Yes. Reading is in our area, within our coverage of Greater London, South East England and Scotland. For a quote, ring 01277 525 020 or email drawings and photos.
What site paperwork can you provide?
Let us know your requirements when you ask for a price. From you, we will need the asbestos information for older buildings and any site rules.
