Mastic sealing in Linchmere

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

Commercial clients in Linchmere

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Linchmere can sit alongside others in a wider programme across West Sussex.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Mastic sealing for commercial buildings in Linchmere

Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. Many prefer a planned programme to one-off visits, with each block quoted and scheduled in turn. Most enquiries involve draught complaints from residents or tenants and estate-wide sealant that is simply worn out, on window and door perimeters on blocks, balcony and threshold joints and communal entrances and stairwells. Whoever orders the work in Linchmere, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

In and around smaller places like Linchmere, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

What happens if it’s left?

Resealing ahead of leaks keeps it to a maintenance task. Once water has tracked in, the repair list grows, and the complaints come with it. Halls, stores and units around places like Linchmere may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

Why clients in Linchmere choose us

Looking after buildings in and around Linchmere

Linchmere has two 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. Rainfall across the South East, Linchmere included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.

If you own or manage units on a site such as Kings Road Industrial Estate (1.8 miles north-east of Linchmere), failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. Site managers at schools like Woolmer Hill School can fit frame mastic into the summer works.

Linchmere is about 9 miles north-east of Petersfield, in West Sussex. Our applicators travel to Linchmere for work on mastic joints, handled exactly as we handle every other area. Our West Sussex coverage takes in 373 places. There’s a separate page for Portsmouth, roughly 23 miles from Linchmere.

If you need mastic sealing in GU27, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. If your building is just outside Linchmere, we cover Hammer Bottom (1 mile north), Woolmer Hill (1 mile north-east), Hammer (1 mile north-east), Shottermill (2 miles north-east) and Bramshott Chase (2 miles north). A short drive away, we cover Billingshurst (14 miles east), Midhurst (6 miles south), Pulborough (14 miles south-east), Petworth (9 miles south-east), Easebourne (6 miles south) and Rudgwick (14 miles east).

Linchmere: questions and answers

Will you take on a block within reach of Liphook station?

Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.

Will you work in a care home in Linchmere without moving residents out?

Yes. Care settings are planned area by area, at times agreed with the home. Any site rules, from signing in to infection control, are agreed before we start.

Do you guarantee the mastic work?

Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.

Is Linchmere in your area?

Yes. Sites across Linchmere are covered, and the same phone number covers every area.

Is asbestos a concern with old mastic?

In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

Who decides which product is used?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Signs you need mastic sealing in Linchmere

Many failed joints were sealed without backing rod so the mastic is bonded on three sides. That three-sided adhesion stops it stretching and splits as the building moves.

Look out for the following:

  • Movement joints with sealant missing
  • Draught complaints from residents or tenants
  • No planned programme for sealant
  • Mastic failing across several blocks on an estate

Trustees of buildings like The Parish Church of St Peter can bring frame and external mastic into a planned maintenance list.

What to look for in a quote

  • Whether their applicators hold CSCS cards
  • The terms of the workmanship guarantee
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • What level of public liability insurance do they hold?

Choosing a commercial sealant contractor

When something else is needed

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Asbestos-containing sealant, which we don’t remove
  • Masonry that has broken away beside the joint
  • Leaks from above rather than through a joint

If in doubt, give us a call on 01277 525 020 or use the quote form and we’ll say what we think.

Joints and surfaces we work on

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

What the job involves on each surface

Tenement and older buildings

Older mastic can contain asbestos and the register is checked before anything is disturbed. If it’s suspected, work stops until it’s tested.

Estate-wide resealing programmes

An estate of similar buildings suits a rolling programme. Each block is priced and scheduled in order.

Diagnose, treat, sign off

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. For work around Linchmere, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. We inspect each building and record the joints that have failed.
  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. Old mastic is removed and the joint faces prepared.
  5. Joints are resealed and tooled.
  6. Each building is checked and signed off with the 12-month guarantee.

Preparing the site

  • Move anything stored against the joints
  • Warn occupants and staff about the work
  • Explain the parking and delivery arrangements
