What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes anything from an hour or two to a full day, depending on how many frames there are, and the area is left clean. Somewhere like Puttenham needs a little journey planning: 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 check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- 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.

FAQs for Puttenham
Can you help a landlord with a rental near Cheddington station?
Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Do you cover smaller places like Puttenham?
Yes. Puttenham is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will explain our choice.
Will resealing my frames help with draughts?
In many cases. The gap between frame and wall is a common source of draughts, and resealing inside and out closes it.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
How long will my window job take?
A few frames take a few hours. You’ll get a timescale with the 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 and we’ll plan for it.
Can you do the inside joint as well?
Yes. Plenty of draughts come through the inside joint as well as the outside, so sealing both is often worthwhile.
When something else is needed
A few problems are outside what sealant work can do:
- A failed sealed unit that has misted up
- A sash or casement that will not close properly
- Draughts through the window seals rather than the frame
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.
Surfaces we seal
- Window sills
- uPVC windows
- Patio & French doors
- Composite doors
- Aluminium frames

DIY sealant or a professional job?
If you’re 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 does not work out, we can still put it right.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Frames and glazing around Puttenham
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Ascott House (about 4.9 miles north) are a reminder that the area around Puttenham has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
In the older streets around Church of St Mary (Church of England), the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For landlords with property near Cheddington station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Leave it or put it right?
Not every sealant suits a window. Interior caulk and bathroom silicone are not made for exterior frame joints. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Around Puttenham, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.

What we are called out for in Puttenham
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
Look out for these signs:
- Mastic that has split away from the wall
- A bead that doesn’t match the frame
- Cracked internal joints between frame and plaster
- Gaps left after new windows were fitted
Managing a site like Long Marston VA Church of England Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.
Questions to ask before you book
- What happens if they find a problem under the old sealant
- Is the old sealant removed completely?
- What preparation is included
- How long to leave it before use

What else we do in Puttenham
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Avoid blasting the frames with a pressure washer
- Repaint timber before it’s bare
- Wash the frames with mild soapy water
- Keep solvents and bleach off the sealant
Silicone can’t normally be painted, so if you are planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
