Need construction mastic in Furnace Wood?

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

On site: what to expect

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Jobs in and around smaller places like Furnace Wood are usually planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. We start with the drawings, specification and programme.
  2. Quantities are measured and a fixed price returned.
  3. We agree with the site team which areas come first.
  4. Plots or floors are sealed as they’re handed over.
  5. Joints are prepared, backed and sealed to the specification.
  6. Snags are cleared and the package signed off with our 12-month guarantee.

Preparing the site

  • Arrange parking or a loading space
  • Agree which areas must stay open
  • Let building users know which areas are affected

Request a quote

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Construction mastic in Furnace Wood

Since 2005 we have worked alongside main contractors, developers and fit-out firms. We price from drawings and the specification, agree the sequence with the site team and seal as areas are released. For construction mastic on a scheme in Furnace Wood, send drawings through our quote form, or phone or email us to talk it through. We work on internal decorators’ caulk, window and door perimeters and brick and block movement joints, and the usual reasons a site gets in touch are inconsistent sealant finishes from plot to plot and bath and shower joints scraped during the final clean. One point of contact handles commercial sealant work in Furnace Wood from the first photographs to the final walk-round, for single jobs and planned programmes alike.

In the countryside around places like Furnace Wood, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Keeping the joints sound

Regular inspection catches problems early. In particular:

  • Put any product change through the designer first
  • Bring the mastic contractor in after the last trades are through
  • Allow flexibility for external sealing in damp or cold weather
  • Ask installers to correct oversized gaps first

Any damage after we have finished should go on the snag list straight away. Snags can be picked up in a planned close-out visit as agreed in the quote.

Leaving the mastic snag list to the end squeezes everyone. Clearing snags area by area spreads the work out and keeps handover on track.

Quoting for work in Furnace Wood

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

  • Removal of failed or old sealant
  • Any access equipment needed
  • Travel to remote or island sites
  • Specialist products, such as fire-rated or hygienic sealants

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Before you send an enquiry

A good diagnosis starts with the right details. Tell us:

  • The type of building and who uses it
  • Photos of the joints, close up and from further back
  • Rough lengths or quantities, or drawings if you have them
  • Asbestos survey details if the building is older

Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings you can plan around. For a chat about it beforehand, speak to us on 01277 525 020 or send photos by email.

For managing agents and facilities managers

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:

  • Designing joint widths or choosing the specification (that sits with the designer)
  • Frame gaps too wide for sealant, which the installer needs to correct
  • Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)

If in doubt, speak to us on 01277 525 020 or send details through our quote form and we will say what we think.

Joints and surfaces we work on

  • Brick and block movement joints
  • Window and door perimeters
  • Internal decorators’ caulk
  • Floor and skirting junctions
  • Cladding and panel joints
  • Sanitary and kitchen joints

FAQs: Furnace Wood

Does your area include sites such as Silverwood Industrial Estate, near Furnace Wood?

Yes. Our area takes in Furnace Wood and its surroundings, with estates and business parks such as Silverwood Industrial Estate included. Photos and a short description are enough for a first look.

Can you work on a hospital site such as Queen Victoria Hospital?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

When can you be on site?

Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.

How long does a typical visit take?

That varies with the scale of the job, though a typical visit typically takes a day or two on a small fit-out and several weeks on a large multi-storey package. For bigger or phased jobs, we will set out a timescale with the quote.

Can one quote cover more than one building?

Yes. Several buildings can share a single quote, with one point of contact.

Do you do fire-rated sealing on new builds?

Fire-rated sealing at service penetrations and linear gaps can be included where specified. Record requirements are confirmed at quote stage.

Are you insured?

Yes. We are fully insured, and the certificate can go with your quote.

Should maintenance staff do it?

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
