Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Window mastic for homes and businesses in Sulhamstead Abbots
Around Sulhamstead Abbots we seal all kinds of frames: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. If you have a bead that doesn’t match the frame and gaps between the frame and the inside reveal, we can put it right, on composite doors, patio & French doors and aluminium frames alike.
Somewhere as small as Sulhamstead Abbots, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
You are covered for a year from the day we finish. If anything isn’t right with it, call 0345 464 0079 or send us an email.

When it is not the sealant
Honest advice matters more to us than a booking, so here’s what new sealant will not do:

What window mastic looks like in Sulhamstead Abbots
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Theale station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. If you look after a building such as Sulhamstead and Ufton Nervet School, larger buildings have plenty of frames, and the mastic around each one ages.

Leave it or put it right?
Choosing the product is half the job. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. Older cottages and farmhouses around Sulhamstead Abbots can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
Why choose Mr Mastic in Sulhamstead Abbots
- We leave the area clean and tidy
- An ARBOMaster approved applicator
- Quality sealants from Arbo and Everbuild
- A sealant colour to suit the surroundings
What we’re called out for in Sulhamstead Abbots
Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. When that sealant fails, water gets into the wall or under the frame.
Common reasons people contact us include:
- Black, perished sealant on frames
- Sealant in the wrong colour for the frame
- Cracked internal joints between frame and plaster
- Draughts coming in around windows and doors
Homes close to Church of St Mary include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How to look after the new joints
A little care helps the new joints last. We recommend:
- Keep solvents and bleach off the sealant
- Walk round the house once a year and look at the joints
- Keep paint off silicone joints
- Keep drainage slots and sill grooves clear
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
Leaks usually show up in wet, windy weather, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
What we do, step by step
On the day, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before work begins. The work generally takes most of a day for a typical house, less for a few frames. Somewhere as small as Sulhamstead Abbots, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit
- Move anything stored near the joints
- Mention if the joints have been sealed before
- Mention any parking rules near the property
