- Untidy mastic left by window fitters
DIY versus a professional finish
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.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Window mastic in Ashurst Wood, done properly
Homes in Ashurst Wood have every kind of window: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. Typical jobs include rushed sealant from a window installation and cracked or shrunken mastic around the frame, on uPVC windows, timber windows & doors and composite doors.
Around Ashurst Wood, 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.

Different surfaces, different methods
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain can’t run into the wall.
Patio & French doors
Patio and French doors have the longest joints on most houses. The threshold and the bottom corners take the most water, so we pay close attention there.

Windows and doors in Ashurst Wood
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Hammerwood Park (about 1.9 miles north-east) nearby, there’s older building stock in the area around Ashurst Wood as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
If you live in an older home near St Dunstan, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For site and facilities teams at buildings such as Ashurst Wood Primary School, larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near East Grinstead station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Looking after it afterwards
To keep the joints looking good and working properly:
- Keep solvents and bleach off the sealant
- Keep paint off silicone joints
- Clear any debris from frame drain holes
- Avoid blasting the frames with a pressure washer
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just phone 0345 464 0079 or send us an email.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. A new joint closes it up.
What happens if it’s left?
Draughts and leaks don’t always mean new windows. If the frames and glass are in good order, resealing the joints is often all that is needed. Problems with the glass or gaskets are for a window company, and we will say so. Older cottages and farmhouses around Ashurst Wood can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Ashurst Wood questions
I let a flat near East Grinstead station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.
Is Ashurst Wood in your area for window mastic?
Yes. We work across London and the South East, and Ashurst Wood is part of that. Just ring 0345 464 0079 or email us with a few details of the job.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and you’ll get one quote.
How many windows can you do in a day?
The work takes a morning for a couple of windows and a door. Access and the amount of old mastic make the biggest difference.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Is the new sealant paintable?
Silicone generally won’t take paint. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Can you seal the gap between the frame and the plaster indoors?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We do one or both.
What happens on the day
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes most of a day for a typical house, less for a few frames. In a small place like Ashurst Wood, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit
- Let us know about parking restrictions
- Mention any tricky access
- Where the joints are inside, avoid wetting them before we arrive
