When to call us in Hinton Waldrist
Mastic ages in the weather. Sunlight dries the surface out, until it loses its stretch and starts to crack.
It’s worth asking for a quote if you see:
- White mastic on grey or black frames
- Gaps between the frame and the inside reveal
- Gaps where the sill meets the wall
- Old mastic that has gone black or come away
In the older streets around Church of St Margaret, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
What your quote should include
- How the surfaces are prepared before sealing
- What the cure time is
- How much experience the applicator has
- Whether the sealant suits the joint

What else we do in Hinton Waldrist
Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Clear any debris from frame drain holes
- Don’t paint over the silicone
- Keep jet washers away from the mastic
- Walk round the house once a year and look at the joints
Check the drainage slots in the frames are not blocked, so water can run away instead of sitting against the joint.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
Honest limits
In fairness, some problems need a different trade:
- A failed sealed unit that has misted up
- A door that needs adjusting, rehanging or new seals
- Soft or decayed wood in the frame
If in doubt, ring 0345 464 0079 or email us and we will say what we think before you book.
What we seal
- Patio & French doors

The process
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a morning for a couple of windows and a door. Somewhere like Hinton Waldrist needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
Preparing for the visit
- Move anything stored near the joints
- Let us know if you’ve seen damp or leaks
- Mention any parking rules near the property

How we quote for window mastic
Your quote is based on your job. We take into account:
- Whether there’s mould to deal with
- How much there is to do
- The type of sealant required
- Whether old sealant or filler has to be cut out
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.
What we need to know
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- A few photos by email, if you can
- Roughly how big the job is
- Access, such as stairs, a lift or height
- The problem you’ve noticed
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. When it suits you, phone 0345 464 0079 or send us an email.
DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

Hinton Waldrist 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. Historic houses like Longworth House (about 0.4 miles north-east) are a reminder that the area around Hinton Waldrist has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Managing a site like Longworth Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.
