About our fire stopping in Sherfield on Loddon
Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. We work to the product’s tested detail for every seal rather than guesswork. Site teams most often ask us about unsealed penetrations discovered above suspended ceilings and expanding foam used as fire stopping, across pipe penetrations, service gaps in risers and linear gaps at wall heads. Searching for sealant specialists in Sherfield on Loddon? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Smaller places such as Sherfield on Loddon still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
We stand by our work with a 12-month guarantee. That covers our preparation and application.

Keeping the joints sound
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Flag new cables with no seal around them
- Check risers and ceiling voids after each round of works
- Settle who seals which penetrations at the start of a project
- Record which product was used where
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Some fire-rated sealants accept paint and some don’t, so check the product data first.
Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.
What we can’t put right
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Reviewing a building’s overall fire safety
- Gaps in walls that were never built as compartment walls
- Plastic pipes whose detail calls for a collar or wrap
If in doubt, speak to us on 01277 525 020 or send photos by email and we’ll say what we think before you book.

Do you need fire stopping in Sherfield on Loddon?
Most open service penetrations are left by later work. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser leaves an opening that nobody returns to. Across several fit-outs, the openings add up.
It’s worth sending us details if you spot any of the following:
- Fire stopping installed outside its tested range
- Fire seals cut back for extra cables and never reinstated
- Hidden openings found during inspections
- Open linear gaps along the top of fire-resisting walls
Tenant changes at parks like Campbell Court Office Park, 0.9 miles to the north-west of Sherfield on Loddon, bring new data and services, and openings through fire-resisting walls need the specified seal.

How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
What do you charge?
Every job gets its own fixed quote. For yours, speak to us on 01277 525 020 or email the details over with a description of the work.
How long before the joints can be used?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
How do I request a quote?
There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.
Do you seal on top of existing sealant?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Should maintenance staff do it?
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
