Waddesdon homes and the weather
Historic houses like Waddesdon Manor (about 0.7 miles west) are a reminder that the area around Waddesdon has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
For landlords with property near Aylesbury Vale Parkway station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Homes close to St Michael and All Angels' Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Waddesdon: your questions answered
Do you cover Waddesdon for window mastic?

What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Do the sealants smell?
There can be a smell while the sealant cures. Opening a window helps.
Is the new sealant paintable?
It depends on the sealant. Silicone isn’t paintable, but some hybrid sealants are. Tell us if you are decorating and we will choose accordingly.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or send us an email.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
How the job changes by surface
uPVC windows
We clean the frame edge carefully so the plastic isn’t marked, then the new bead is laid against the frame and the wall.
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. The bead is colour-matched to the frame.

What we are called out for in Waddesdon
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. A sealant that can’t keep up eventually tears.
People generally contact us when they notice something like this:
- Rushed sealant from a window installation
- Cracked or shrunken mastic around the frame
- Damp patches on the reveal after heavy rain
- Sealant in the wrong colour for the frame
Managing a site like Waddesdon Village Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

The process
On the day, we start by going over the job with you. Surfaces next to the work are protected before any work begins. The work normally takes a few hours for a few frames, or a day or more for a whole house. In a small place like Waddesdon, access is normally 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.
- 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.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Keep children and pets away from the work area
- On commercial sites, let us know about site rules
- Mention any tricky access

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Leave it or put it right?
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. Older cottages and farmhouses around Waddesdon can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we’ll go through it with you.
