Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
How the quote is worked out
To price the job, we consider:
- How accessible the joints are
- Site requirements such as inductions and permits
- How much existing material needs removing
- Whether the work must be split into stages
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
Details that help us quote
A few photographs plus some basic facts will normally do. It helps to include:
- Drawings or a marked-up plan, if available
- The site address and postcode
- Specification clauses that apply
- What the building is and how it’s used
Need a figure for a tender or a budget? Send the scope and any drawings, and we’ll return a fixed quote that you can work with. If you have questions first, speak to us on 01277 525 020 or send photos by email.
About our fire stopping in Dedham Heath
For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. We work from your penetration schedule or marked-up drawings. Tell us what records you need and we’ll confirm with the quote. If you’re dealing with fire stopping installed outside its tested range and fire-rated sealant that has cracked or shrunk back, we can help. Whoever orders the work in Dedham Heath, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Smaller places such as Dedham Heath still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
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 are clear about what is covered before work starts.

After the work
A few simple habits keep the new joints working:
- Put resealing into every M&E and fit-out package
- File the specified details where the next contractor can find them
- Leave fire sealant to cure fully before covering it
- Arrange inspection before areas are covered up
Allow the manufacturer’s stated cure time before boxing in or decorating. Not every fire-rated product can be painted.
Regular walk-rounds of service areas are worth the time. Catching a damaged seal early keeps the fix small; found late, it can be one of many.

Where services cross fire walls in Dedham Heath
The area within 2 miles of Dedham Heath holds several hotels. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail. Fire stopping of openings and penetrations in England falls under Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Either way, we install the specified product to its tested detail.
In a building such as Parish Church of St Mary, any service penetration through a fire-resisting wall should be sealed to the specified detail. Industrial units on estates such as Martells Industrial Estate, 2.1 miles south of Dedham Heath, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal. On a hospital site such as Severalls Hospital (4.7 miles west of Dedham Heath), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

For managing agents and facilities managers
Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.
What the job involves on each surface
Metal pipes
Heat travels along metal pipework. If the detail needs something beyond sealant, we tell you.
Cables and cable bundles
New data and power cables are the most common breach we see. We reseal around them to the specified detail, and any bundle too large for sealant alone is flagged.
Should maintenance staff do it?
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
From enquiry to sign-off
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. For work around Dedham Heath, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.
- First we go through the drawings, schedule or specification for the seals.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Preparing the site
- Flag any permit to work we will need
- Send asbestos survey details if the building is pre-2000
- Explain the parking and delivery arrangements

Advice
Questions we are asked in Dedham Heath
How does the move away from BS 476 affect penetration seals in Dedham Heath?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Can you seal around new services in a hotel near Dedham Heath?
Yes, where fire-rated sealant is the specified product. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we’ll tell you if the detail calls for a collar, wrap or batt instead.
Is any job too small?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
