How we handle mastic sealing in Boyatt Wood

We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. A planned, building-by-building programme often works better than reacting to each complaint and we quote and schedule each building in turn. The enquiries we see most involve a mix of products and colours from past repairs and estate-wide sealant that is simply worn out, on communal entrances and stairwells, balcony and threshold joints and window and door perimeters on blocks. One point of contact handles commercial sealant work in Boyatt Wood from the first photographs to the final walk-round, whether it’s one building or several.

In a smaller place such as Boyatt Wood, landlords and agents tend to look after small blocks, flats over shops, sheltered housing and commercial units. The mastic around their frames and external joints ages like anywhere else.

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant.

When it isn’t the sealant

Some faults sit outside our scope, and we say so rather than covering them up:

  • Failed window or door frames, which need a window contractor
  • Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
  • Misted or failed double-glazed units

If in doubt, give us a call on 01277 525 020 or use the quote form and we will say what we think before you book.

Joints and surfaces we work on

  • Communal kitchens and washrooms
  • Window and door perimeters on blocks
  • External wall and movement joints
  • Shopfronts below residential blocks
  • Communal entrances and stairwells
  • Balcony and threshold joints

Doing it in-house

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, 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. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

For managing agents and facilities managers

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Frames, entrances and external joints in Boyatt Wood

Boyatt Wood is about 65 miles from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. Rainfall across the South East, Boyatt Wood included, is lower than in many parts of the UK. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first.

Churches, halls and community buildings such as St. Peter's Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. For a school such as Crestwood Community School, perimeter mastic on windows and doors is a holiday job. If you manage student housing near a university such as University of Southampton, which lies south-west of Boyatt Wood, the summer turnaround is the time for mastic.

Common questions from Boyatt Wood clients

Will you take on work at estates like Boyatt Wood Industrial Estate, close to Boyatt Wood?

Yes, sites like Boyatt Wood Industrial Estate are within our area, along with the rest of Boyatt Wood. Send details of the unit and the work through our quote form for a quick quote.

Is Boyatt Wood too far out for you?

No. Places such as Boyatt Wood are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Who decides which product is used?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Can weather delay the job?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Do you need to see the site first?

Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we will arrange a visit before quoting.

How do you reach windows on upper floors?

It depends on the building. How upper joints are reached is agreed before work is booked so there are no surprises.

Can you reseal a whole block or estate?

Block-wide and estate programmes are common. You get a fixed quote per building or for the whole job.

Different surfaces, different methods

Tenement and older buildings

Stone needs a neutral-cure product and we choose accordingly.

Planned maintenance

Planned resealing replaces emergency callouts and spreads the work.

Looking after the joints

For the best life from the joints:

  • Prioritise elevations facing the weather
  • Protect low-level joints in entrances
  • Make it easy for occupiers to report draughts
  • Check sealant joints during planned building inspections

Protect entrance and corridor joints from knocks where possible. Knocks cause many early failures in communal areas.

One failed perimeter usually means others on the same building are close, so it pays to look at the whole elevation. A planned reseal saves repeated visits.

Our process

Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. Work in places the size of Boyatt Wood is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.

  1. First we look at the mastic on each building and note what needs replacing.
  2. You get a fixed quote, priced per building where that helps your budgeting.
  3. The programme is fixed with you, including dates you can pass on to residents or tenants.
  4. Failed mastic is removed and the faces taken back to sound, dry material.
  5. Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
  6. Finished joints are looked over and the 12-month guarantee confirmed.

Getting the site ready

  • Explain the parking and delivery arrangements
  • For older buildings, check the asbestos register before work
  • Send any specification or drawings in advance
