Mastic sealing for Woolstone sites

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

Work for main contractors and building owners

Building owners and managing agents use us on everything from one building to a spread of sites around Woolstone. One quote can cover more than one site, so there’s one set of paperwork to deal with.

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Mastic sealing for commercial buildings in Woolstone

Blocks are lived in, so access and disruption have to be thought through. The sequence, the areas and the dates are settled with you, giving you what you need to notify residents. Entrances and stairwells are kept in use throughout. We work on window and door perimeters on blocks, communal entrances and stairwells and balcony and threshold joints, and the usual reasons a site gets in touch are the same joint failures repeated across a portfolio and repeated reactive repairs to the same buildings. Whoever orders the work in Woolstone, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Owners with buildings around smaller places like Woolstone often group mastic work so one visit covers several properties. One quote can cover a whole list of addresses.

Work we carry out 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’ll arrange a return visit.

When it isn’t the sealant

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

  • Glazing that needs replacing
  • Roof leaks, gutters or failed flashings that aren’t sealant joints
  • Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)

Not sure which it is? You can ring 01277 525 020 or send photos by email and we will tell you honestly.

  • Communal kitchens and washrooms
  • Communal entrances and stairwells

Questions about Woolstone

Can work in a care setting near Woolstone go ahead while residents are there?

Yes. We agree rooms and times with the manager and work a few areas at a time. Tell us about any infection-control or safeguarding requirements and we will work to them.

Do you cover business parks and estates near Woolstone, such as Woodlands Business Park?

Yes, sites like Woodlands Business Park are within our area, along with the rest of Woolstone. Photos and a short description are enough for a first look.

How many days will you need on site?

That varies with the scale of the job, though a typical visit normally takes a few days for most blocks, with larger programmes scheduled building by building. For bigger or phased jobs, we’ll set out a timescale with the quote.

Can you take on resealing for a block portfolio?

Yes, that’s exactly who this service is for. We work through buildings in a planned order so you can plan around it.

What will the job cost?

There isn’t a price list, because every site is different. Send photographs or drawings and we will price it at a fixed figure.

Does the weather affect the work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Will you quote for a small job?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

Diagnose, treat, sign off

Tell us your site hours and access windows and we will plan around them. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. What matters most for a job in Woolstone is a clear list of what needs doing, so send photos of each area. You’ll then get a fixed price for the work.

  1. A building-by-building inspection lists the failed joints.
  2. You get a fixed quote, per block or for the whole programme.
  3. Dates and areas are agreed so occupiers can be told.
  4. Failed sealant is removed and the faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. We check the finished work and confirm the guarantee.

Getting the site ready

  • Share your working hours and any access restrictions
  • Tell us what induction or permit system the site runs
  • Warn occupants and staff about the work

What we’re called out for in Woolstone

Communal entrances and corridors see a lot of wear, with joints near the floor and around doors suffering most. Regular cleaning wears them further.

It’s worth sending us details if you spot any of the following:

  • The same joint failures repeated across a portfolio
  • Damp patches beside frames
  • Failed external movement joints
  • Repeated reactive repairs to the same buildings

Schools and community buildings such as Shepherdswell Academy need frame and external mastic kept sound like any building.

Before you book anyone

  • Will failed sealant be removed rather than covered?
  • Can the work be phased to keep areas open?
  • Are they CHAS accredited or on Constructionline?
  • How the joint faces will be prepared and primed

Questions to ask before you appoint anyone

General trades versus a specialist

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.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Blocks and managed buildings in Woolstone

Woolstone has three care or nursing homes no more than 2 miles away. Owners of care premises can bring window and door mastic into a phased programme planned around the home. Woolstone is in the South East, one of the UK’s drier regions. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first.

With historic buildings such as Linford Manor (to the north-west of Woolstone) in the wider area, owners of older properties around Woolstone should expect mastic to need a product that suits old masonry. Property owners at sites such as Woodlands Business Park (2.1 miles north-west of Woolstone) can have mastic renewed between lettings.

Maintenance after handover

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Prioritise elevations facing the weather
  • Reduce knocks to communal area joints
  • Check sealant joints during planned building inspections
  • Share the asbestos register when you send details

Add mastic joints to your cyclical inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away and record where they are.

Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings so spending is spread.
