Mastic sealing in Lyndhurst
Across Lyndhurst and the rest of Hampshire, we work the same way: send details, get a fixed quote, we seal, and the work is guaranteed. A list of buildings, a few photographs and approximate joint numbers are enough for a quick quote or we can visit. We work on communal kitchens and washrooms, window and door perimeters on blocks and communal entrances and stairwells, and the usual reasons a site gets in touch are repeated reactive repairs to the same buildings and draughts at frames across a block. For commercial sealant work in Lyndhurst, you deal with one contact from quote to sign-off, whether it’s one building or several.
Places the size of Lyndhurst typically have some housing association stock, small blocks and mixed-use buildings. Their window perimeters and external joints need renewing as the mastic ages.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

Do you need mastic sealing in Lyndhurst?
Sunlight and weather break mastic down over time. The surface chalks, the body stiffens and cracks appear most of all on the sunniest and most exposed elevations.
Any of the following is a good reason to get the joints checked over:
- Leaks at window and door perimeters
- Communal area joints that look neglected
- Movement joints with sealant missing
- A mix of products and colours from past repairs
For a school such as St Michael and All Angels CofE Infant School, perimeter mastic on windows and doors is a holiday job.
Questions to ask before you book
- Are they CHAS accredited or on Constructionline?
- Their approach to joint depth and backing
- The named product and why it was chosen
- How the joint faces will be prepared and primed
Honest limits
Honesty saves time and money. New sealant won’t cure:
- Asbestos-containing sealant, which we don’t remove
- Substrate edges that need repairing first
- Failed window or door frames, which need a window contractor
If you’re not sure, just speak to us on 01277 525 020 or email the details over and we’ll give you a straight answer before you book.

Blocks and managed buildings in Lyndhurst
Lyndhurst sits in one of the drier corners of the country, the South East. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first.
If you look after a block within reach of Ashurst New Forest station, 2.4 miles north-east of Lyndhurst, frame and balcony mastic can be renewed on one programme. If you are responsible for a building such as Church of Our Lady and St Edward, frame and door mastic needs the same attention as any other property.

What else we do in Lyndhurst
After the work
After handover, a little attention goes a long way:
- Track which buildings were done and when
- Share your contractor requirements early
- Encourage occupiers to report problems at frames
- Check the asbestos register before any old mastic is disturbed
Keep records of when each building was resealed. That makes future programmes easier to plan and shows what was done.
Budgets are easier to plan when sealant is part of planned maintenance. We can quote buildings in priority order so spending is spread.
FAQs: Lyndhurst
Is a smaller place like Lyndhurst outside your area?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can one quote cover a number of our buildings near Lyndhurst?
Yes. Planned programmes across a building, block or estate are a core part of this service. Residents are given notice through you, and the work moves building by building.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Is asbestos a concern with old mastic?
Some mastics in pre-2000 buildings contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Do you supply RAMS and insurance details?
Our credentials include CHAS, Constructionline and public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Does the weather affect the work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
On site: what to expect
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Work in places the size of Lyndhurst is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- A building-by-building inspection lists the failed joints.
- The quote is fixed and split as suits you.
- We agree the programme and dates with you.
- Failed sealant is removed and the faces prepared.
- Joints are resealed and tooled.
- Each building is checked and signed off with the 12-month guarantee.
Preparing the site
- Point out any areas we must not close
- Explain the parking and delivery arrangements
- Share your working hours and any access restrictions
Quotes
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Quoting for work in Lyndhurst
Before we quote, we look at:
- Induction, permit and paperwork requirements
- Joint width, depth and condition
- Location, for remote and island sites
- Access and working height
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.
Details that help us quote
However big the job, the same details help:
- Specification clauses that apply
- Rough lengths or quantities, or drawings if you have them
- The type of building and who uses it
- When you need the work done
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to speak to us on 01277 525 020 or send photos by email with what you know.
When to bring in a specialist
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
