Construction mastic in Peasemore

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Maintenance after handover

Regular inspection catches problems early. In particular:

  • Share drawings and the specification as soon as possible
  • Don’t force external sealing on a damp or frosty day
  • Note which sealant went where at handover
  • Stick to the specified sealant rather than a generic substitute

The package carries our 12-month guarantee for workmanship. Damage by others isn’t a workmanship fault, so protecting sealed areas matters.

Snag items left to the last week put handover at risk. A planned close-out through each area as it completes keeps the list short and keeps handover on track.

Construction mastic for commercial buildings in Peasemore

Mastic tends to be one of the final packages before handover, which puts it right on the critical path. We work as a mastic subcontractor to main contractors and developers with projects in Peasemore, following the trades through the building as rooms and elevations become ready. Most enquiries involve old sealant on a refurbishment that needs stripping before new work and snag items on joints that need redoing before handover, on window and door perimeters, sanitary and kitchen joints and brick and block movement joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Peasemore is the same: the right product in a properly prepared joint.

Around smaller places like Peasemore, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

Work we carry out in West Berkshire comes with a 12-month guarantee. If an installation problem shows up, give us a call on 01277 525 020 or use the quote form and we will arrange a return visit.

When to call us in Peasemore

Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A sealant that isn’t right for the substrate or the movement will fail ahead of time. We stick to the specified product, or put any alternative to you first.

What tends to prompt an enquiry:

  • Missed perimeter joints on a new elevation
  • Different trades sealing to different standards
  • Sealant knocked or painted over by other trades
  • Mastic snags holding up handover

A facade joint near Peasemore lasts when width, depth and backing are right, not just the finish.

What your quote should include

  • The terms of the workmanship guarantee
  • Are they CHAS accredited or on Constructionline?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • What site paperwork they can supply

Choosing a commercial sealant contractor

For managing agents and facilities managers

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Questions about Peasemore

What documents will you need to give us for a job in Peasemore?

We’ll confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.

Can you keep pace with our programme in Peasemore?

Yes, we work to the programme and the sequence the site sets. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Do you need to see the site first?

That depends on the size and complexity of the job. Simple work can often be priced from photographs, and bigger or more complex jobs normally get a visit.

Does weather matter for sealant work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

When can you be on site?

We’re in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

Do you guarantee new-build sealant work?

Each package is backed by a 12-month guarantee. We are also fully insured for public liability.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.

Sites and facades in and around Peasemore

At about 54 miles from central London, Peasemore is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme. Rainfall across the South East, Peasemore included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager.

On any site in or around Peasemore, the mastic follows the specification and the programme.

What sealant work can’t fix

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

  • Joints damaged after sign-off by following trades
  • Approving fire stopping as compliant
  • Specifying the product where the designer hasn’t

If in doubt, ring 01277 525 020 or send details through our quote form and we will say what we think before you book.

What we seal

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

Diagnose, treat, sign off

Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. If others near Peasemore need work, visits can be combined. A fixed quote is given before anything starts.

  1. First we look at the scope on site or from drawings.
  2. You receive a fixed quote covering scope, products and sequence.
  3. Paperwork is agreed and applicators are inducted on site.
  4. Sealing follows the programme as areas are released.
  5. Problems we find, such as oversized gaps, are raised right away.
  6. The package is closed out, snags cleared and backed by our 12-month guarantee.

What we need from you

  • Make sure the joints can be reached
  • Tell us your opening times and when work is allowed
  • Point out any areas we must not close

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Fire-rated sealant where specified

Fire-rated sealant is one type of fire-stopping product. Collars, wraps, batts and boards are specified for other services so we will flag where the detail needs something different. Tell us what records you need and we’ll confirm with the quote.

Internal decorators’ caulk

Caulking is often done in a hurry by whoever’s on site. A neat, consistent caulk line makes the decorators’ job quicker and keeps the snag list down.
