Surface by surface
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 they get particular care.
Composite doors
Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. We match the colour to the frame.
About our window mastic in Hinxton
Around Hinxton we seal all kinds of frames: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We work on uPVC windows, window sills and patio & French doors, and the jobs we see most are white mastic on grey or black frames and draughty joints inside around the window.
Mastic can only go onto a dry, clean joint, so window work in Hinxton is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Each job carries a 12-month guarantee.

Leave it or put it right?
Working on frames from a ladder with a sealant gun isn’t easy, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. In a small place like Hinxton, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and agree the price before starting.

How to look after the new joints
Looking after new joints is easy:
- Clear any debris from frame drain holes
- Paint up to the joint, not over it
- Ventilate rooms so frames do not stay wet inside
- Wash the frames with mild soapy water
Most silicone sealants won’t take paint, so mention any painting plans before any work starts. We can use a paintable sealant where that matters.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. A new joint closes it up.
Work for landlords, hotels and businesses
We also work for property managers and facilities teams. Several sites can be quoted together.

Your questions about window mastic in Hinxton
Can you help a landlord with a rental near Whittlesford Parkway station?
Yes. We work for landlords and agents as well as homeowners. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Do you cover smaller places like Hinxton?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint before we leave.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
What does window mastic cost?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
What information do you need?
A short description and the location. If we need more, we’ll ask.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Hinxton homes and the weather
With historic houses such as Audley End House (about 4.8 miles south) nearby, there’s older building stock in the area around Hinxton 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’s traditional sand mastic. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Whittlesford Parkway station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. In the older streets around Parish Church of St Mary and St John the Evangelist, the joint between an old wall and a newer frame is normally the first place rain gets in.

Quotes for window mastic in Hinxton
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The number of rooms or windows
- How easy the joints are to reach
- Any mould that needs treating
- How much there is to do

What happens on the day
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes most of a day for a typical house, less for a few frames from start to finish. In a small place like Hinxton, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.

Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
