Common problems we fix in Upper Eddington
Scraping and sanding before painting can loosen old mastic. Many people find it crumbling when they prepare the windows, which is a good time to renew it.
People usually contact us when they notice one of these:
- Open joints round the window box
- Old cement repairs round a window that have failed
- Mastic round period door frames that has failed
- Crumbling sand mastic round a window
If you look after a building such as Hungerford Primary School, its window and door frames need their mastic kept sound, just like a home’s.
Before you book anyone
- What preparation is included
- Who does the work, and how experienced they are
- Is the old sealant removed completely?
- Which sealant they’ll use, and why
Why deal with it now?
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall so renewing it early protects the window. In a small place like Upper Eddington, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, ring 0345 464 0079 or send us an email and we will give you an honest view and a quote.
Why book with us
- Over 20 years’ experience
- Neat joints and a tidy finish
- We’re fully insured
- Approved under the ARBOMaster scheme
Aftercare tips
How long the joints last depends on use and care. We suggest:
- Check the mastic when you check the paintwork
- Keep modern sealant off the mastic
- Make sure water runs off the sill
- Avoid heavy scraping on the mastic joint
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry so early renewal protects both.
Different surfaces, different methods
Period and listed homes
Materials matter on listed and conservation-area homes. Like-for-like sand mastic is generally favoured.
Tenement and terrace windows
Upper-floor windows need access planning. Tell us the height and we’ll confirm what’s needed.
Upper Eddington homes and the weather
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around Hungerford Methodist Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For landlords with property near Hungerford station, older sash windows in a rental need their mastic kept sound to keep the weather out.
