Mastic sealing in Bouldnor

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

Mastic sealing in Bouldnor, done properly

Blocks are lived in, so access and disruption have to be thought through. Dates, areas and the order of work are agreed with you in advance so you can let residents know what is happening. Entrances and stairwells are kept in use while we work. If you have open joints in brickwork or panels and water getting in round frames after rain, we can put it right. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Bouldnor it comes down to the same thing: 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 Bouldnor 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.

Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Mastic sealing in Bouldnor: the local picture

The sea is no more than about 1 mile from Bouldnor. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first, so it’s worth inspecting those sides more often. Bouldnor is in the South East, one of the UK’s drier regions. Outside work still depends on dry joints, and the sunniest, most exposed sides of a building typically need attention first.

For agents with blocks near Lymington Pier station, 4.2 miles to the north-west of Bouldnor, a block-wide mastic programme deals with frames, balconies and entrances in one go. If you are responsible for a building such as Church of St Swithin (old), frame and door mastic needs the same attention as any other property. With historic buildings such as Mottistone Manor, 4.4 miles south-east of Bouldnor, in the wider area, owners of older properties around Bouldnor should expect mastic to need a product that suits old masonry.

Bouldnor is about 5 miles south-east of Lymington, in the Isle of Wight. We cover Bouldnor, with the same fixed quotes and 12-month guarantee as everywhere else. Bouldnor is one of 125 places in the Isle of Wight on our list. Sites around Southampton have their own page, roughly 15 miles from Bouldnor.

If you need mastic sealing in PO41, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. If your site is on The Vineyard, Port La Salle and Waters Edge or close by, send details and we’ll quote for mastic joints. Just outside Bouldnor, we also work in Yarmouth (1 mile west), Cranmore (1 mile east), Hamstead (2 miles north-east), Shalfleet (3 miles east) and Thorns Beach (4 miles north). Nearby towns on our patch include Newport (8 miles east), Ryde (14 miles east), Cowes (8 miles north-east), Sandown (14 miles east), Shanklin (14 miles east) and Ventnor (14 miles south-east). For island and remote sites, travel and materials need planning ahead, so the full address helps from the start.

Work for main contractors and building owners

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.

Leave it or put it right?

Open external joints let water into walls and around frames. Damp patches, stained plaster and decorating claims can follow and those cost far more to put right. Older rural buildings around Bouldnor move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

A quote for mastic joints depends on quantities, condition and access, and any specification that applies. Call for a quote.

What sealant work can’t fix

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Roof leaks, gutters or failed flashings that aren’t sealant joints
  • Glazing that needs replacing
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first

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

Where we work in Bouldnor

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

Different surfaces, different methods

Commercial and mixed-use buildings

Commercial buildings have mastic at shopfronts, entrances and external joints. A planned programme suits multi-building portfolios.

Tenement and older buildings

Some old mastics in pre-2000 buildings contain asbestos, so we check the asbestos register or survey first. If it’s suspected, work stops until it’s tested.

Aftercare for building managers

Cleaning and maintenance staff play a part too. Share these points with them:

  • Plan resealing building by building rather than complaint by complaint
  • Start inspections with the most exposed faces
  • List the paperwork your organisation requires when you send details
  • Ask residents or tenants to report leaks and draughts early

Keep records of when each building was resealed. It helps plan the next round and gives you a history.

Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.

On site: what to expect

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs in and around smaller places like Bouldnor are typically planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. We inspect each building and record the joints that have failed.
  2. The quote is fixed and split as suits you.
  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. Each building is checked and signed off with the 12-month guarantee.

What we need from you

  • Tell us what induction or permit system the site runs
  • Share the asbestos register for older buildings
  • Clear stock, furniture or equipment away from the joints

Request a quote

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Bouldnor: questions and answers

Is Bouldnor too small for you to travel to?

Not at all. Bouldnor is within our area. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.

Will you take on a block within reach of Lymington Pier station?

Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Send the address, photographs of the elevations and your access arrangements, and we will give a fixed quote.

Do you check for asbestos in old sealant?

Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.

How long does a typical visit take?

The duration is planned around your programme and the access we’re given. We will give you an estimate of time on site when we quote.

When is resealing likely to be due?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Do you work with property factors and landlords?

Yes, block and estate work is a core part of what we do. We work through buildings in a planned order with dates agreed in advance.

Is it fine to apply new sealant on top of old?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
