Windows and doors in Bovingdon Green
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. With historic houses such as Harleyford Manor (about 1.7 miles south) nearby, there’s older building stock in the area around Bovingdon Green as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Managing a site like Spinfield School? Then larger buildings have plenty of frames, and the mastic around each one ages. Letting a property close to Marlow station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

Why deal with it now?
Once mastic fails, rain can get between the frame and the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. A reseal is a much smaller job. Where a wall is exposed, as many are in small places like Bovingdon Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, phone 0345 464 0079 or drop us an email and we will give you an honest view and a quote.
Why book with us
- Colour agreed with you before work begins
- Anti-fungal silicone where joints get wet
- We leave the area clean and tidy
- Old sealant always removed completely
The process
You don’t need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes a morning for a couple of windows and a door in most cases. In a small place like Bovingdon Green, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Before we arrive
- Clear items away from the joints we’re working on
- Let us know about stairs, lifts or work at height
- Let us know if you’ve seen damp or leaks

Different surfaces, different methods
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A tidy bead in anthracite grey, black or a matching colour suits the frame.
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We’ll tell you which suits your home.
DIY versus a professional finish
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. 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.
For landlords and businesses
For anyone letting property in or around Bovingdon Green, jobs at different addresses can go on one quote. Send us the addresses and the work at each.
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
What sealant work cannot fix
New sealant can’t fix everything, and we’ll tell you before we start. Sealant will not put right:
- Draughts through the window seals rather than the frame
- Condensation trapped between the panes
- Damp problems in the wall away from the window
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly.
Joints and surfaces we work on
- Composite doors
- Aluminium frames
- Patio & French doors
- Timber windows & doors
- uPVC windows
- Window sills
When to call us in Bovingdon Green
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, while a joint packed solid cannot stretch. That’s what backing rod is for.
People generally contact us after spotting something like this:
- Water coming in at the bottom corners of a door
- Draughty joints inside around the window
- Hard, cracked sealant around windows
- Untidy mastic left by window fitters
For an older house near a landmark such as Congregational Church, the joint between an old wall and a newer frame is generally the first place rain gets in.
What your quote should include
- The length of the guarantee
- Which sealant they’ll use, and why
- What happens if they find a problem under the old sealant
- Whether they seal over old material or remove it
