Mastic sealing across Boldre

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

Mastic sealing for commercial buildings in Boldre

We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. Many prefer a planned programme to one-off visits, with each block quoted and scheduled in turn. If you have worn sealant at communal door frames and window mastic that has split and shrunk, we can put it right, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Boldre is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Owners and agents with buildings around smaller places such as Boldre tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

When something else is needed

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Masonry that has broken away beside the joint
  • Leaks from above rather than through a joint
  • Broken glass or failed sealed units

Not sure which it is? You can phone 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.

Mastic sealing in Boldre: the local picture

With the shore within about 2 miles, Boldre counts as a coastal location. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints, and they deserve more regular inspection. The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building typically need attention first.

Older community buildings, Saint Nicholas Chapel among them, often have frames of mixed ages whose mastic varies. For agents with blocks near Lymington Town station, which lies south-east of Boldre, a block-wide mastic programme deals with frames, balconies and entrances in one go. Site managers at schools like William Gilpin Church of England Primary School can fit frame mastic into the summer works.

Boldre is about 2 miles north of Lymington, in Hampshire. Businesses, contractors and managing agents in Boldre can call on us for mastic joints. We work across 723 places in Hampshire, from busy centres to rural villages. Southampton is covered too, some 12 miles away.

Postcode districts covered here: SO41. Buildings on Tweed Lane, Boldre Lane and Rope Hill are within our area for mastic joints. Just outside Boldre, we also work in Warborne (1 mile south-east), Battramsley (1 mile north-west), Pilley (1 mile east), Sandy Down (1 mile north-west) and Mount Pleasant (1 mile west). Bigger towns within reach include Totton (10 miles north), Hedge End (14 miles north-east), Romsey (15 miles north), Hythe (9 miles north-east), New Milton (5 miles west) and Ringwood (11 miles north-west).

Site staff or a sealant specialist?

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

What the job involves on each surface

Estate-wide resealing programmes

An estate of similar buildings suits a rolling programme. We quote building by building and work through them in turn.

Window and door perimeters on blocks

Blocks have a mix of frame materials, so the grade we pick has to bond to frame and wall alike. We will confirm the colours available for the specified product.

Boldre: questions and answers

Can you quote for a block close to Lymington Town station?

Yes. Managing agents, landlords, property factors and housing associations are who this service is for. We work to your notice and access arrangements.

Can being near the sea in Boldre affect the sealant we need?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

How do you handle work on occupied blocks?

We plan around people living or working in the building. We agree the programme so you can notify occupiers and communal access is kept open.

What about access for upper-floor joints?

Access is discussed and agreed before the quote is fixed. Tell us the number of storeys and whether scaffold or other access is planned and we’ll confirm the approach in the quote.

Is asbestos a concern with old mastic?

In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.

Do you work in Boldre?

Yes. We cover Boldre, and you can ring 01277 525 020 or send details through our quote form to get started.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Aftercare for building managers

To get the most from the new sealant:

  • List the paperwork your organisation requires when you send details
  • Reduce knocks to communal area joints
  • Avoid piecemeal callouts where you can
  • Have the asbestos survey to hand for older buildings

Log the date and extent of the resealing for each block. That makes future programmes easier to plan and gives you a history.

Left open, joint edges in render, brick or frames can deteriorate. Then the edges may need repairing first.

For managing agents and facilities managers

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Boldre can sit alongside others in a wider programme across Hampshire.

Our process

On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself typically taking anything from a day to a few weeks, depending on the number of buildings and joints. If others near Boldre need work, visits can be combined. You’ll have a fixed quote before work starts.

  1. We inspect the joints, building by building, and record what has failed and why.
  2. A fixed quote follows, split by block or building if that suits you.
  3. The programme is fixed with you, including dates you can pass on to residents or tenants.
  4. We remove the old mastic completely and clean the joint faces back.
  5. Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
  6. Each building is checked on completion and the work carries our 12-month guarantee.

Preparing the site

  • Tell us which areas need to stay in use
  • Send asbestos survey details if the building is pre-2000
  • Have the specification and drawings to hand

Getting a fixed quote

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.
