Fire stopping across Medstead

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

What we are called out for in Medstead

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.

Things that typically lead to an enquiry:

  • Snag lists that include open service penetrations
  • Builders’ foam or ordinary silicone in compartment walls
  • Hidden openings found during inspections
  • Improvised or mixed-product fire seals

Schools such as Medstead Church of England Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

What your quote should include

  • Who will actually carry out the work
  • The terms of the workmanship guarantee
  • Their plan for phasing and protecting the area
  • Their pre-qualification and accreditations

Our contractor checklist

Fire stopping in Medstead

On a fit-out or refurbishment, we follow the services contractors floor by floor. We work from your penetration schedule or marked-up drawings. Tell us what records you need and we will confirm with the quote. We work on joints between fire-resisting walls and floors, linear gaps at wall heads and small duct penetrations where the tested detail allows, and the usual reasons a site gets in touch are openings found when ceilings come down for a refit and non-fire-rated filler around services. A specialist sealant contractor works differently from a general builder: on jobs in Medstead, preparation and product choice get the time they need.

Around Medstead, penetration and linear seals tend to be one-building jobs. Send the specification, drawings or photographs of the openings and we’ll quote to suit.

Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

How a job runs

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work usually takes a single visit for a short list of penetrations, or a phased programme for a whole building. What matters most for a job in Medstead is a clear list of what needs doing, so send photos of each area. A fixed quote follows.

  1. We read the specification, drawings or penetration schedule you send.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. Mineral wool or other backing goes in wherever the detail asks.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Preparing the site

  • Tell us which areas need to stay in use
  • For older buildings, check the asbestos register before work
  • Confirm the product named in the specification

Quotes

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.

FAQs: Medstead

Does your area include sites such as Mansfield Business Park, near Medstead?

Yes. We cover Medstead and the area around it, including industrial estates, business parks and retail parks such as Mansfield Business Park. Send details of the unit and the work through our quote form for a quick quote.

What happens to BS 476 references for fire stopping in Medstead?

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

What’s the quickest route to a quote?

There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.

What hours do you work?

Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.

How much does the work cost?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we will price it properly.

Will you quote for a small job?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

Can the sealant be colour-matched?

It depends on the product specified. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.

What we can’t put right

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Reviewing a building’s overall fire safety
  • Construction that lacks the fire resistance the seal relies on
  • Plastic pipes whose detail calls for a collar or wrap

If you’re not sure, just speak to us on 01277 525 020 or use the quote form and we will give you a straight answer before you book.

What we seal

  • Joints between fire-resisting walls and floors
  • Cable penetrations
  • Pipe penetrations
  • Linear gaps at wall heads
  • Service gaps in risers
  • Small duct penetrations where the tested detail allows

Fire stopping around Medstead: what changes locally

In England, Approved Document B covers fire stopping of openings and penetrations. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. Medstead is about 49 miles from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.

In a building such as Church of the Good Shepherd, any service penetration through a fire-resisting wall should be sealed to the specified detail. On a site such as Mansfield Business Park, under half a mile to the south-east of Medstead, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product.

Medstead is about 4 miles south-west of Alton, in Hampshire. We cover commercial sites throughout Medstead, for single jobs and planned programmes alike. Medstead is one of 723 places we cover in Hampshire. For work in that direction, see our Southampton page.

Leave it or put it right?

An unsealed opening affects more than fire safety: they also carry noise, draughts and smells between rooms. Sealing them to the specified detail deals with the fire risk first. In a smaller place such as Medstead, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we’ll explain how it’s made up.

Why choose Mastic Doctor in Medstead

  • Fixed quotes based on photographs, drawings or a visit
  • Workmanship guaranteed for 12 months
  • One contact handling all your sites
  • Sealing commercial buildings since 2005

Maintenance after handover

A few simple habits keep the new joints working:

  • Keep product data and details in the fire safety file
  • Ask the designer to confirm details early on refits
  • Look above ceilings when tiles are lifted for other jobs
  • Don’t let anyone top up a fire seal with the wrong product

Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original unless the designer specifies otherwise.

A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate, and it helps at inspections.

Work for main contractors and building owners

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Medstead can sit alongside others in a wider programme.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
