Window mastic for homes and businesses in Rout's Green
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We are fully insured ARBOMaster approved applicators, and we give a one-year guarantee on the work. We work on timber windows & doors, patio & French doors and uPVC windows, and common reasons people get in touch are black, perished sealant on frames and sealant in the wrong colour for the frame.
Around Rout's Green, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Big or small, you get the same 12-month guarantee.

How the job changes by surface
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A tidy bead in anthracite grey, black or a matching colour keeps the clean look.
Patio & French doors
Door frames take knocks and movement every time the doors are used. A flexible sealant copes with that.
Rout's Green: your questions answered

Frames and glazing around Rout's Green
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like West Wycombe Park House (about 3.6 miles south-east) are a reminder that the area around Rout's Green 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, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For landlords with property near Saunderton station, renewing tired window mastic between tenants heads off draught and damp complaints.

How the visit works
When we arrive, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. Most jobs take a morning for a couple of windows and a door. In a small place like Rout's Green, 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.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Keep children and pets away from the work area
- Tell us about access, such as stairs, a lift or high-level joints

Related advice
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Don’t paint over the silicone
- Check the mastic once a year
- Wipe condensation off the frames
- Keep timber frames painted
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

When to call us in Rout's Green
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar didn’t grip properly, so it comes away long before its time.
People usually contact us after spotting one of these:
- Rain getting in at the frame or under the sill
- Whistling draughts around closed windows
- Gaps between the frame and the inside reveal
- Hard, cracked sealant around windows
Managing a site like Bledlow Ridge School? Then the mastic around its windows and doors needs looking after like any other building’s.

Asking for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Access, such as stairs, a lift or height
- A few photos by email, if you can
- The rough size of the job

Why act early in Rout's Green
Getting a straight, even bead on an outside frame takes practice, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. Where a wall is exposed, as many are in small places like Rout's Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
