Quoting for work in Dean Street
Each job is priced on its own details. The things that drive the figure:
- Site requirements such as inductions and permits
- The size and state of each joint
- Quantities, in metres or numbers
- Whether old sealant has to be cut out first
The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
Details that help us quote
Diagnosis starts before we arrive. Let us know:
- The product your specification calls for
- Any dates the work must fit around
- Anything awkward about access or site hours
- Photos of the joints, close up and from further back
Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. To get it moving, give us a call on 01277 525 020 or send details through our quote form.
Fire stopping for commercial buildings in Dean Street
A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, often unnoticed. Those on your schedule are closed with the specified product. We work on small duct penetrations where the tested detail allows, cable penetrations and linear gaps at wall heads, and the usual reasons a site gets in touch are fire stopping installed outside its tested range and open linear gaps along the top of fire-resisting walls. Searching for sealant specialists in Dean Street? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Around smaller places like Dean Street, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, speak to us on 01277 525 020 or email us and we will come back to it.

What happens if it’s left?
Sealing behind the M&E trades area by area beats a sweep at the end. Openings are visible, access is open and nothing has to be taken down and each detail can be checked as we go. Older rural buildings around Dean Street move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.

FAQs: Dean Street
Is a smaller place like Dean Street outside your area?
No. Places such as Dean Street are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
How does the move away from BS 476 affect penetration seals in Dean Street?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Will you just go over the old sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
How do we ask for a quote?
You can use the quote form on this site; alternatively, phone 01277 525 020 or email us. Include photos or drawings if you have them.
Do you take on small jobs?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

What else we do in Dean Street
Keeping the joints sound
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Report damaged or disturbed seals as soon as they’re spotted
- Include service cupboards in routine inspections
- Agree the fire-stopping specification before services go in
- Foam or ordinary sealant is never a fire-seal repair
During planned inspections, look at seals in risers, cupboards and voids. Watch for cracked sealant, new services with no seal and openings that have grown.
Make reporting new openings part of every permit to work in service areas. It costs little and catches breaches early.
Our process
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Rural sites near Dean Street may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- The specification and schedule come first, so we know which details apply.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
Before we start on site
- Explain the parking and delivery arrangements
- Flag any permit to work we will need
- Send asbestos survey details if the building is pre-2000

Compartments and services around Dean Street

Our part stays the same: the specified product, installed to its tested detail. Dean Street lies roughly 31 miles out from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.

What sealant work can’t fix
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Plastic pipes whose detail calls for a collar or wrap
- Reviewing a building’s overall fire safety
- Deciding what a wall or floor needs, which belongs to the designer
If in doubt, ring 01277 525 020 or send details through our quote form and we’ll say what we think.
