How we handle window mastic in Boldre
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We are ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. If you have hard, cracked sealant around windows and a bead that doesn’t match the frame, we can help, whatever the surface.
Around Boldre, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Each job carries a 12-month guarantee, large or small.

When to call us in Boldre
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
It’s worth asking for a quote if you see:
- Draughts coming in around windows and doors
- A bead that does not match the frame
- Black, perished sealant on frames
- Gaps where the sill meets the wall
For landlords with property near Lymington Town station, renewing tired window mastic between tenants heads off draught and damp complaints.
What to look for in a quote
- How hidden problems are handled
- The length of the guarantee
- How much experience the applicator has
- Whether they seal over old material or remove it
What affects the quote in Boldre
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Mould in or behind the old joints
- The number and length of the joints
- How easy the joints are to reach
- The type of sealant required
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Roughly how big the job is
- How we’d reach the joints
- The address or postcode of the job
- Pictures of the joints, sent by email
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, ring 0345 464 0079 or drop us an email.
How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Check the mastic once a year
- Make sure the drainage slots aren’t blocked
- Clean frames with a soft cloth and soapy water
- Avoid blasting the frames with a pressure washer
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.

Common questions in Boldre
Is window mastic in a coastal place like Boldre any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Do you cover smaller places like Boldre?
Yes. Boldre is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or email us.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Where are you based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Can landlords and businesses book you?
Yes, regularly. Several properties can be quoted together.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Work for landlords, hotels and businesses
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Surface by surface
Window sills
Where a sill meets brick or render, the ends often crack first. A tight seal at each end keeps rain out of the wall.
Aluminium frames
Aluminium needs a sealant that bonds to coated metal, and acetoxy silicones are not used, as they can attack some metals. Neutral-cure sealant is the safe choice.
What sealant work cannot fix
To be straight with you, some problems need a different trade:
- Rotten timber, which needs a joiner first
- A sash or casement that won’t close properly
- Misting between the panes of a double-glazed unit (that needs a new unit)
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.

How it works
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes a morning for a couple of windows and a door. For a village or hamlet like Boldre, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about stairs, lifts or work at height
- Let us know about earlier repairs to the joints

Advice
Window mastic in Boldre: local notes
Boldre is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near Saint Nicholas Chapel, the joint between an old wall and a newer frame is usually the first place rain gets in. For site and facilities teams at buildings such as William Gilpin Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.
