The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a few frames, or a day or more for a whole house and we leave things clean and tidy. For a job in Oakfield, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- 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.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
How to prepare
- Mention any parking rules near the property
- Where the joints are inside, avoid wetting them before we arrive
- Mention any tricky access

Advice
Window mastic in Oakfield, done properly
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through. Where the air is getting in through the window itself, we’ll say so. If you have old mastic that has gone black or come away and draughty joints inside around the window, we can put it right, on aluminium frames, composite doors and timber windows & doors alike.
Many houses in smaller places like Oakfield have conservatories, garden rooms or patio doors. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.
Each job carries a 12-month guarantee, whatever its size.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
For landlords and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will quote.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
What the job involves on each surface
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
Composite doors
Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.
Common problems we fix in Oakfield
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
Most people get in touch after spotting something like this:
- Rushed sealant from a window installation
- Gaps where the sill meets the wall
- Old mastic that has gone black or come away
- Draughts coming in around windows and doors
If you live in an older home near St John's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Questions to ask before booking
- What product goes in the joint
- Whether all the old sealant comes out first
- What the quote includes, VAT included or not
- How much experience the applicator has
Window mastic in Oakfield: local notes
Oakfield is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Historic houses like Nunwell House (about 2.6 miles south) are a reminder that the area around Oakfield has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For landlords with property near Ryde St Johns Road station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Managing a site like Dover Park Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Check the mastic once a year
- Keep paint and stain on wooden frames in good order
- Don’t paint over the silicone
- Do not aim a pressure washer at the joints
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.
