What we do, step by step
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from an hour or two to a full day, depending on how many frames there are. For a village or hamlet like Piddington, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking each window and door with you.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Getting ready for the visit
- Tell us if parking is tricky
- Move anything stored near the joints
- Let us know about earlier repairs to the joints

Common questions in Piddington
Will you come out to Piddington?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Saunderton station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. You can call 0345 464 0079 or email us with the details for a clear quote.
Can you do the inside joint as well?
Yes. Inside, the joint between frame and plaster is sealed neatly.
How many windows can you do in a day?
A handful of frames is a short visit, while a whole house takes longer. We confirm the timing with your quote.
Can you reach windows above the ground floor?
Yes, as long as they can be reached safely. Tell us about access when you get in touch so we can plan the job.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used before we leave.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
How the job changes by surface
uPVC windows
uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. We match white, brown, anthracite grey and black frames.
Patio & French doors
Heavy door frames can move more than windows. A flexible sealant copes with that, where a rigid one would crack.
What sealant work can’t fix
To be straight with you, some problems need a different trade:
- A sash or casement that won’t close properly
- A door that needs adjusting, rehanging or new seals
- Penetrating damp from a failed cavity tray or render
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.

How we quote for window mastic
There’s no set price list, because jobs vary so much. What we look at:
- The product the joint needs
- Whether there’s mould to deal with
- The number and length of the joints
- The old material and how stubborn it is
Doing several joints on one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We will send you a clear quote for the lot.
What we need to know
Photos by email are helpful but not essential. Please mention:
- If it’s domestic, commercial or a hotel
- Pictures of the joints, sent by email
- Any previous sealing or DIY work
- What’s wrong with the joints now
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. Whenever you are ready, ring 0345 464 0079 or send us an email.
What window mastic looks like in Piddington
Historic houses like West Wycombe Park House (about 1.1 miles east) are a reminder that the area around Piddington has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near St Lawrence's Church, the joint between an old wall and a newer frame is usually the first place rain gets in.

Landmarks near Piddington
Typical jobs here are in homes near The Brickmakers Arms, among other places. Piddington’s nearest station is Saunderton station, about 2.5 miles north of the centre. A little further out are High Wycombe Castle (3.5 miles east) and Wycombe Hospital (3.4 miles east). Green spaces nearby include Yoesden.
Common problems we fix in Piddington
Sun, frost and rain wear sealant out. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
Any of these means the joints need attention:
- Gaps left after new windows were fitted
- Mastic that is falling out in pieces
- Sealant in the wrong colour for the frame
- Mastic that has split away from the wall
Letting a property close to Saunderton station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
Questions to ask before booking
- How the joint is cleaned and prepared
- Is the old sealant removed completely?
- What happens if the job turns out different
- Whether VAT is included
Why it’s worth doing now in Piddington
Working on frames from a ladder with a sealant gun isn’t easy, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. Older cottages and farmhouses around Piddington can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
