Window Mastic in Brockenhurst
We cover Brockenhurst for mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Gaps left after new windows were fitted
- Cold air getting in at the frame edge
- Leaking joints at the ends of sills
Window mastic in Brockenhurst
The new joint doesn’t have to be white. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. If you have rain getting in at the frame or under the sill and black, perished sealant on frames, we can put it right, whatever the surface.
Many houses in smaller places like Brockenhurst have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows.
You are covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or send us an email.

Brockenhurst: your questions answered
Do you work for landlords with property near Brockenhurst station?
Yes, we work for landlords and agents. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.
Is Brockenhurst within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Does the work come with a guarantee?
Yes, for 12 months. A yearly look at the joints helps them last.
Can you reach windows above the ground floor?
Yes, where it’s safe. For high or awkward windows, we’ll tell you what access is needed.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few photos.
Where are you based?
We are based in Crawley, and we cover South East England, London and all of Scotland.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Frames and glazing around Brockenhurst
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Brockenhurst station? Then renewing tired window mastic between tenants heads off draught and damp complaints. If you live in an older home near Church of St Saviour, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What’s near Brockenhurst
Around Brockenhurst, our work takes us to homes and buildings near Morant Arms and the streets around them. Brockenhurst has its own railway station: Brockenhurst station. Nearby you’ll also find Lymington New Forest Hospital (3.8 miles south).
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Look round the frames every year or so
- Keep jet washers away from the mastic
- Keep solvents and bleach off the sealant
- Air rooms to keep condensation down around windows
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.
What we can’t put right
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- A sash or casement that will not close properly
- Rotten timber, which needs a joiner first
- Penetrating damp from a failed cavity tray or render
If you are not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer.
What we seal
- Patio & French doors
- Timber windows & doors
- Aluminium frames
- Window sills
- uPVC windows
- Composite doors
When to call us in Brockenhurst
Sills take more water than any other part of a window, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.
Look out for these signs:
- Cracked or shrunken mastic around the frame
- Leaking joints at the ends of sills
- Water coming in at the bottom corners of a door
- A bead that does not match the frame
If you look after a building such as Brockenhurst Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.

The process
All our tools and materials come with us in the van. Once we have agreed what’s being done, we protect the area and start. Most jobs take a morning for a couple of windows and a door. A visit to Brockenhurst is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Let us know about parking restrictions
- Where the joints are inside, avoid wetting them before we arrive
- Move anything stored near the joints

Advice
Landlords, agents and businesses in Brockenhurst
Landlords and agents in Brockenhurst can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
If you manage several properties in or around Brockenhurst, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs.
Why deal with it now?
Resealing frames is a short job: the visit takes most of a day for a typical house, less for a few frames. Leave it until water is coming in and you may need plastering and decorating as well. In an older home around Brockenhurst, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we will explain what it covers.
