How we handle fire stopping in Lamb Corner
On a fit-out or refurbishment, we follow the services contractors floor by floor. To price a package, ring 01277 525 020 or email a schedule or drawings with the schedule or marked-up drawings and the specified product data. Tell us what records you need and we’ll confirm with the quote. If you are dealing with snag lists that include open service penetrations and head-of-wall gaps with no fire seal, we can help, on joints between fire-resisting walls and floors, service gaps in risers and pipe penetrations alike. Searching for sealant specialists in Lamb Corner? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Rural conversions around Lamb Corner can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

When it isn’t the sealant
We check first that sealant really is the fix. It won’t put right:
- Openings that need collars, wraps, batts or boards rather than sealant
- Writing the fire-stopping specification
- Gaps in walls that were never built as compartment walls
If in doubt, ring 01277 525 020 or email the details over and we will say what we think.
What we seal
- Cable penetrations
- Service gaps in risers
- Pipe penetrations
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
What the job involves on each surface
Drylining partitions
Plasterboard partitions are tested as a specific construction. The sealant detail has to be tested in that wall type, with the stated board layers before sealing.
Linear joints
Head-of-wall joints often have to absorb slab deflection. We use the product and backing the detail names for that movement.
Cost factors for service penetrations
Before we quote, we look at:
- Site requirements such as inductions and permits
- The product specified
- Phasing around occupants
- Removal of failed or old sealant
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
What we need to price the job
For an accurate fixed quote, we need a clear picture of the site. Useful things to include:
- What the building is and how it’s used
- Approximate linear metres or a joint schedule
- When you need the work done
- How the joints are reached, and at what height
For a fixed quote, phone 01277 525 020 or email drawings and photos. Our quote form is another easy route.
Doing it in-house
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.
There’s also the paperwork. 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.
Our process
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. If others near Lamb Corner need work, visits can be combined. You’ll have a fixed quote before work starts.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- Old or wrong materials are cut out.
- Mineral wool or other backing is fitted where required.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- Completed areas are checked with you, with the records agreed when we quoted.
Getting the site ready
- Move anything stored against the joints
- Warn occupants and staff about the work
- For older buildings, check the asbestos register before work
Ask for a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

What else we do in Lamb Corner
Compartments and services around Lamb Corner
In England, Approved Document B covers fire stopping of openings and penetrations. 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. A 2-mile radius around Lamb Corner takes in 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.
For a building such as Parish Church of St Mary, new heating or data runs are the usual reason penetrations need sealing. Schools such as Dedham Church of England Voluntary Controlled Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

Lamb Corner: questions and answers
Is Lamb Corner too far out for you?
No. Places such as Lamb Corner are covered as much as the big towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.
Do you seal service penetrations in hotels around Lamb Corner?
Yes. We install fire-rated and intumescent sealant where it is specified. Each seal follows the tested detail, and rooms are done in turn.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
What site paperwork can you supply?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Do you take on multi-site work?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
How long does a job like this take?
It depends on the scope, though a typical visit typically takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. For bigger or phased jobs, we will set out a timescale with the quote.
Can you quote from photographs?
It depends on the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.
What we are called out for in Lamb Corner
When a seal departs from its tested detail, the evidence no longer covers it. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are the usual culprits.
Look out for the following:
- Fire stopping installed outside its tested range
- Expanding foam used as fire stopping
- Openings left by services added after handover
- Unsealed joints where partitions meet the slab
Tenant changes at parks like Blue Barns Business Park (1.5 miles south-west of Lamb Corner) bring new data and services, and openings through fire-resisting walls need the specified seal.
What your quote should include
- How the joint faces will be prepared and primed
- Their public liability cover
- How joint depth will be controlled
- Their pre-qualification and accreditations
