Window mastic in Beech
Over two decades of sealing frames has taught us which products suit which walls. We are ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. Typical jobs include black, perished sealant on frames and draughts coming in around windows and doors, across window sills, uPVC windows and patio & French doors.
Somewhere as small as Beech, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
All our work is covered by our 12-month guarantee.

Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Don’t use solvent cleaners on the joint
- Walk round the house once a year and look at the joints
- Wash the frames with mild soapy water
- Clear any debris from frame drain holes
Silicone cannot normally be painted, so mention any painting plans before work begins. There are paintable sealants for joints that need it.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.

Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Are you insured?
Yes. We are fully insured, and we can confirm the details when we quote.
Can you do several jobs on one visit?

Can you do the inside joint as well?
Yes. Indoors, we seal between the frame and the plaster or reveal.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you.
Can new sealant go over the old?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
How the visit works
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a morning for a couple of windows and a door. For a village or hamlet like Beech, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Plan for the work area to be out of bounds to pets and children
- Tell us about any water getting in

Advice
DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Why it’s worth doing now in Beech
Choosing the product is half the job. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Around Beech, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Why choose Mr Mastic in Beech
- Quality sealants from Arbo and Everbuild
- We’re fully insured

Landlords, agents and businesses in Beech
For anyone letting property in or around Beech, several properties can go on one quote. Just tell us the addresses and what each one needs.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Honest limits
New sealant can’t fix everything, and we will tell you before any work starts. It will not solve:
- Draughts through the window seals rather than the frame
- A frame that has rotted at the joint
- Condensation trapped between the panes
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly before you book.

Beech homes and the weather
With historic houses such as Bentworth Hall (about 1.5 miles west) nearby, there’s older building stock in the area around Beech as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around St Peter's, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Letting a property close to Alton station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. If you look after a building such as Amery Hill School, its window and door frames need their mastic kept sound, just like a home’s.

Different surfaces, different methods
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. Most leaks start at the bottom corners, so we pay close attention there.
Aluminium frames
Coated aluminium needs a compatible sealant. We use a neutral-cure product.
