Little Chesterford: questions and answers
Can you work around term dates at a campus such as St Mark's College?
Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Is Little Chesterford too far out for you?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
How do we ask for a quote?
There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.
Can you handle several sites?
Yes. Several buildings can share a single quote, with one point of contact.
Does the weather affect the work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Is colour matching possible?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.
Do you work in Scotland as well as England?
Our work covers Greater London, the South East and every Scottish council area. Scotland’s non-domestic Technical Handbook, clause 2.1.14, expects service penetrations to be fire stopped to at least the wall or floor’s fire resistance, with proprietary products tested for the end use.
How we handle fire stopping in Little Chesterford
On a fit-out or refurbishment, we follow the services contractors floor by floor. To price a package, call 01277 525 020 or email drawings and photos with the schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we will confirm with the quote. We work on small duct penetrations where the tested detail allows, pipe penetrations and joints between fire-resisting walls and floors, and the failures we’re asked to look at most are open linear gaps along the top of fire-resisting walls and improvised or mixed-product fire seals. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Little Chesterford it comes down to the same thing: the right product in a properly prepared joint.
For a smaller site near Little Chesterford, we plan to do all the penetrations in one go, so send the specification and photos first. Design and sign-off belong to the designer or building control; we install what’s specified.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

From enquiry to sign-off
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs in and around smaller places like Little Chesterford are typically planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- We read the specification, drawings or penetration schedule you send and raise any questions before we price.
- 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
- Send your site hours and access windows
- Send any specification or drawings in advance
- Flag any permit to work we’ll need

Quoting for work in Little Chesterford
These are the things that shape the price:
- How much there is to seal
- Joint width, depth and condition
- Working within restricted access windows
- Induction, permit and paperwork requirements
We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.
What we need to price the job
A few photos plus some basic facts will normally do. It helps to include:
- What the building is and how it’s used
- The asbestos register, for older buildings
- Any specification or named product
- Drawings or a marked-up plan, if available
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
Surface by surface
Small ducts
Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Bigger ducts and fire-resisting ductwork are normally handled with other products, and we will say if that applies.
Linear joints
Head-of-wall joints often have to absorb slab deflection. We use the product and backing the detail names for that movement, with no gaps along the run.
What happens if it’s left?
An unsealed opening affects more than fire safety: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first and the building feels the difference. Halls, stores and units around places like Little Chesterford may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Do you need fire stopping in Little Chesterford?
Plenty of openings were simply never closed, often hidden above suspended ceilings or behind boxing. They come to light during inspections, refits or when another trade lifts a tile.
Most enquiries start with one or more of the following:
- Old intumescent sealant that has split away
- Unsealed joints where partitions meet the slab
- Damaged fire seals in risers and voids
- Expanding foam used as fire stopping
In a building such as Church of St Mary the Virgin, any service penetration through a fire-resisting wall should be sealed to the specified detail.

- What site paperwork they can supply
- Can the work be phased to keep areas open?
- Whether old or failed sealant will be cut out, not overlaid
- What the guarantee covers, and for how long
