St Lawrence: questions and answers
Does your area include sites such as Pioneer Business Park, near St Lawrence?
Yes, sites like Pioneer Business Park are within our area, along with the rest of St Lawrence. Send details of the unit and the work through our quote form for a quick quote.
Is St Lawrence too far out for you?
No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
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.
Is your workmanship covered by a guarantee?
Yes. Our workmanship is backed for 12 months.
Can weather delay the job?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
How do I request a quote?
There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.
Fire stopping in St Lawrence, done properly
No fire sealant works on its own: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. We match each opening to that detail before any sealant goes in, and raise it with you if it falls outside. We work on small duct penetrations where the tested detail allows, pipe penetrations and cable penetrations, and the failures we’re asked to look at most are open linear gaps along the top of fire-resisting walls and seals that don’t match their tested detail. A specialist sealant contractor works differently from a general builder: on jobs in St Lawrence, preparation and product choice get the time they need.
Fire-rated sealing in a place like St Lawrence is normally a single building at a time. Send the specification, drawings or photos of the openings and we will quote to suit.
A 12-month guarantee applies to all our work in Kent. Should something we installed fail, ring 01277 525 020 or send photos by email and we’ll come back to it.

From enquiry to sign-off
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence, and our waste is bagged and taken away as we go. For a site in St Lawrence, we plan so the whole job is done in one go where possible. Clear photographs and measurements help us bring the right products.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned first.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
Preparing the site
- Arrange parking or a loading space
- Confirm the product named in the specification
- Agree which areas must stay open
Quotes
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.
Related advice
Leave it or put it right?
Inspections and handover checks often pick up fire stopping. Finding unsealed or improvised openings late can hold up a programme. For buildings in places like St Lawrence, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

When to bring in a specialist
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
What sealant work can’t fix
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:
- Gaps in walls that were never built as compartment walls
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Large openings beyond what any sealant detail covers
If you are not sure, just call the office on 01277 525 020 or send details through our quote form and we’ll give you a straight answer.
Surfaces we seal
- Cable penetrations
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Service gaps in risers
- Pipe penetrations
- Small duct penetrations where the tested detail allows
When to call us in St Lawrence
Some service penetrations were never sealed at all. Inspections, refurbishments and ceiling access usually bring them to light.
Any of the following is a good reason to get the joints checked over:
- Head-of-wall gaps with no fire seal
- Service penetrations left open after M&E works
- Fire-rated sealant that has cracked or shrunk back
- Expanding foam used as fire stopping
In a retail centre such as Broadstairs Retail Park, which lies north of St Lawrence, any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail.
Questions to ask before you book
- Their approach to joint depth and backing
- How the existing material will be dealt with
- Will RAMS and insurance details be available?
- Do they follow the manufacturer’s priming guidance?
What sets the cost
Quotes vary with the job. Expect it to depend on:
- Location, for remote and island sites
- Working within restricted access windows
- Removal of failed or old sealant
- Any access equipment needed
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
Sending details for a quote
Diagnosis starts before we arrive. Tell us:
- Approximate linear metres or a joint schedule
- Your programme or deadline
- Specification clauses that apply
- Whether the building will be occupied during the work
A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or call 01277 525 020 or email drawings and photos to discuss it first.

What else we do in St Lawrence
Service penetrations in St Lawrence buildings
St Lawrence lies roughly 65 miles out from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls; the gaps need the specified seal. There are a good number of hotels within about 2 miles of St Lawrence. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product.
Hotels like Hotel de Ville, under half a mile to the south-east of St Lawrence, are refurbished in phases, and each phase can open up compartment walls. On a hospital site such as Queen Elizabeth The Queen Mother Hospital, 2.8 miles to the north of St Lawrence, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
