Much window restoration is about looking after the vulnerable windows.
Masonry Restoration walls are also vulnerable and we'll look at those later. So why do window sills need special attention?
Take the case of an attractive oriel window on this Victorian house.
The window is built outside the house footprint making it particularly exposed to the weather.
Sills have suffered from rot due to the hedge growing so near and remaining continually damp between rain showers.
The hedge below this pretty window came from a cutting from Queen Victoria's bouquet.So....
... before we started repairs we had to take care of this special plant by tying it back away from the sill.
After repairs we suggested pruning back the bush to avoid further problems.
The front of this terrace house in Neville Street, Norwich never gets the sun. The
wood stays damp.
The original plinths are gone – not surprising when they are so vulnerable to the rain.
Plinths are the decorative parts that connect to the window ledge.
The columns are concrete with a timber cladding and the plinths sit at the bottom of these columns.
When you look at houses close by this one you'll notice their plinths have all been replaced at some time. All have a different designs. I would say few are original.
Beading is placed on the top to discourage rain water and the plinth is then painted for protection.
The challenge is to make good what you see here.
There is no need to fill the gap as this will be covered over.
From the sketch you can see how the new window restoration covers the rather ugly hole.
The wood came from Cushions Hardwood Division in Norwich.
The job entails:
1) Taking off the existing battens.
2) Treating the exposed cladding with preservative.
3) Making good the area of cladding to the sides or “returns”.
4) Transfer the exact position of the columns corner onto the window ledge. This will help you find the angle for when you mitre the plinths.
5) For the plinths - allow extra
width to allow for mistakes when you are cutting the miters.
6) Screwing and gluing on the new plinths to the face and only then use battens for the returns.
7) Pin and glue window glazing battens on top to complete the job.
8) Protect the timber using primer, undercoat and topcoat. It should then last for years to come.
At another Norwich house further down the same road the building repair required a different treatment. Rotten cills - probably due to a leaking gutter.
When rainwater is continually dripping onto woodwork you are going to get wet rot. So what’s the solution? Well first, repair the leaking gutter if you can. Without your attention a leaking gutter can do a lot of damage to your house.
One way to repair rotten sills is to chisel out the crumbling, rotten areas until you get back to solid wood.
Treat with preservative and when dry use a wood hardener.
Wood filler makes
timber renovations easier than using wood but not any cheaper. I use good quality wood filler.
It dries within the hour and you can sand it down to a neat finish. Ideal for all house renovations. You may well have to use small pieces of wood to help fill the larger voids.
