Fire stopping for businesses in Whitley

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Leave it or put it right?

An improvised seal can look finished while offering no tested performance. The fix is to remove it and reinstall to the detail, so it makes sense to get it right first time. In a smaller place such as Whitley, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Why appoint us

  • Fixed quotes based on photographs, drawings or a visit
  • Commercial sealant work since 2005
  • Work to your specification and the manufacturer’s guidance
  • A Constructionline member, so easy to vet

Fire stopping for commercial buildings in Whitley

Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Other openings need collars, wraps, batts, pillows or boards. We use sealant where it is the specified product, and we tell you when a detail calls for something else. Most enquiries involve improvised or mixed-product fire seals and old intumescent sealant that has split away, on small duct penetrations where the tested detail allows, joints between fire-resisting walls and floors and linear gaps at wall heads. Searching for sealant specialists in Whitley? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

Around smaller places like Whitley, many commercial buildings are conversions or extensions of older ones, so it’s worth confirming the wall or floor type before choosing the seal. The right product depends on the wall or floor and the services passing through, and we’ll tell you if the detail calls for something other than sealant.

Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

What the job involves on each surface

Plastic pipes

Plastic waste pipes through slabs come up often. The detail decides whether sealant alone is enough, and we won’t substitute it for a specified collar.

Risers and ceiling voids

Risers and ceiling voids hold most of a building’s service penetrations. Access to these areas is planned with you in advance, including keys, permits and any isolations.

What we can’t put right

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Writing the fire-stopping specification
  • Plastic pipes whose detail calls for a collar or wrap
  • Signing off or certifying a building’s fire stopping

If you’re not sure, just call the office on 01277 525 020 or use the quote form and we will give you a straight answer.

Joints and surfaces we work on

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

Commercial clients in Whitley

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Whitley can form part of a wider programme.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

FAQs: Whitley

Will you plan work around the academic year at somewhere like University of Reading - Whiteknights Campus?

Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Is a smaller place like Whitley outside your area?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.

How do I request a quote?

You can use the quote form on this site; alternatively, call the office on 01277 525 020 or send photos by email. Include photos or drawings if you have them.

What if there’s asbestos in the old mastic?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

What changes on 2 September 2029?

It mainly affects England, where Approved Document B is dropping its BS 476 references from 2 September 2029. Classification to BS EN 13501-2 becomes the expected evidence, though transitional rules apply. In Scotland, the Technical Handbook sets its own guidance.

Are you insured?

Yes. Mastic Doctor is fully insured, public liability included.

Will you come and look before quoting?

It depends on the job. Simple work can often be priced from photos, and bigger or more complex jobs normally get a visit.

On site: what to expect

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes a single visit for a short list of penetrations, or a phased programme for a whole building, and we clear our waste as we work. For a job in Whitley, the main thing is a clear picture of the work. You will then get a fixed price for the work.

  1. First we confirm the product and tested details named in the specification.
  2. Openings are measured and grouped by detail.
  3. Improvised fillers and failed sealant are removed.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Preparing the site

  • Point out parking and an unloading spot
  • Share the asbestos register for older buildings
  • Flag any permit to work we’ll need

Advice

What sets the cost

Each job is priced on its own details. The things that drive the figure:

  • The size and state of each joint
  • How much existing material needs removing
  • Whether the work must be split into stages
  • The product specified

The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.

Sending details for a quote

It doesn’t need to be a full survey. A few details are enough to get going:

  • The asbestos register, for older buildings
  • The site address and postcode
  • Rough lengths or quantities, or drawings if you have them
  • When you need the work done

Need a figure for a tender or a budget? We’ll quote against your scope and drawings you can plan around. If you have questions first, speak to us on 01277 525 020 or email drawings and photos.

Compartment walls and floors in Whitley

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. Our part stays the same: the specified product, installed to its tested detail. There are plenty of hotels within about 2 miles of Whitley. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product.

Hotels like Reading Hotel, 0.8 miles north of Whitley, are refurbished in phases, and each phase can open up compartment walls. At a college such as Reading College, 1.8 miles north of Whitley, checking penetration seals after summer M&E works is good practice. Residences at universities like University of Reading - Whiteknights Campus (to the north-east of Whitley) have compartment walls that must be resealed whenever services change.

Whitley is about 1 mile west of Earley, in Reading. We cover commercial sites throughout Whitley, for single jobs and planned programmes alike. Our Reading coverage takes in 17 places, from busy centres to rural villages.
