Mastic sealing in Brockenhurst
Blocks are lived in, so access and disruption have to be thought through. The sequence, the areas and the dates are settled with you so you can let residents know what is happening. Entrances and stairwells are kept in use while we work. If you have worn sealant at communal door frames and damp patches beside frames, we can put it right. A specialist sealant contractor works differently from a general builder: in Brockenhurst, that means joint design, primers and backing rod as standard.
Older buildings and conversions around places like Brockenhurst mix old masonry with newer frames. Perimeter joints need a sealant that suits both frame and masonry.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What affects the price in Brockenhurst
Quotes vary with the job. Expect it to depend on:
- Backing rod, priming and other preparation
- Location, for remote and island sites
- Phasing around occupants
- How much existing material needs removing
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.
What we need to price the job
A good diagnosis starts with the right details. Let us know:
- Drawings or a marked-up plan, if available
- Clear photographs of the problem areas

What sealant work can’t fix
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
- Materials that need asbestos testing before work
- Glazing that needs replacing
If in doubt, phone 01277 525 020 or email us and we’ll say what we think before you book.

Signs you need mastic sealing in Brockenhurst
Poor preparation explains many failed joints. Where the faces weren’t cleaned or primed as specified, the bead peels off one side.
Look out for the following:
- Repeated reactive repairs to the same buildings
- Water getting in round frames after rain
- Mastic failing across several blocks on an estate
- Old repairs sealed over failed mastic
For a school such as Brockenhurst Church of England Primary School, perimeter mastic on windows and doors is a holiday job.
Questions to ask before you book

- Health and safety accreditation such as CHAS

Mastic sealing around Brockenhurst: what changes locally
The South East is one of the drier parts of the UK. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first.
Trustees of buildings like Church of St Saviour can bring frame and external mastic into a planned maintenance list. If you look after a block within reach of Brockenhurst station, under half a mile to the south-east of Brockenhurst, frame and balcony mastic can be renewed on one programme.
Brockenhurst is about 5 miles north of Lymington, in Hampshire. We send applicators to Brockenhurst for mastic joints. 723 places across Hampshire fall within our area, including Brockenhurst. There’s a separate page for Southampton, about 11 miles away.

What happens if it’s left?
Dealing with failed joints one report at a time is slow and scattered. A planned programme treats each building once, under a single quote and a single programme. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.
A quote for mastic joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

We keep entrances and stairs open throughout. Work is planned in sections.
Your questions answered
Can one quote cover a number of our buildings near Brockenhurst?
Yes, we quote for single buildings and for programmes across several blocks. Residents are given notice through you, and the work moves building by building.
We manage a building near Brockenhurst station. Can you help?
Yes, and several blocks can go on one quote. Photos of each elevation help us quote accurately.
Will residents or tenants be disturbed?
The work is planned around occupiers. We agree the programme so you can notify occupiers and communal access is kept open.
How many days will you need on site?
It depends on the scope, but the work typically takes a day or two for a single block, longer for an estate programme. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Do you work for managing agents and housing associations?
Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.
Do you seal on top of existing sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
