Frames and glazing around Nutbourne
With historic houses such as Old Place Manor (about 1.8 miles west) nearby, there’s older building stock in the area around Nutbourne as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as St Mary's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Rented homes near Pulborough station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

Mastic can only go onto a dry, clean joint, so window work in Nutbourne is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

What we are called out for in Nutbourne
Most of it is simply age. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
The problems people normally mention when they call include:
- Mastic that needs renewing before redecorating
- A silicone bead on a sash window that spoils the look
- Open joints round the window box
- Draughts and rain around sash boxes
Schools such as West Chiltington Community Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
What your quote should include
- How long to leave it before use
- Whether they seal over old material or remove it
- Whether you can choose the colour
- Which sealant they’ll use, and why
What happens on the day
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours per window, depending on the condition of the joints. Somewhere like Nutbourne needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.

- Clear the area around the work

What else we do in Nutbourne
Why act early in Nutbourne
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic is the like-for-like choice and that can be important for listed homes. In a small place like Nutbourne, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before work begins.

Surface by surface
Timber door frames
Doors face weather and wear and the mastic can crack early. It’s renewed by hand.
Stone surrounds
Sand mastic sits naturally against stone. The finish blends with the masonry.
DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
If you manage several properties in or around Nutbourne, several properties can go on one quote. Just tell us the addresses and what each one needs, and pictures by email help.
Aftercare tips
So the new joints stay in good condition:
- Have rotten timber repaired before new mastic goes in
- Ask us before painting near the mastic
- Plan mastic work ahead of painting
- Don’t run silicone over sand mastic
Don’t touch or press the mastic while it hardens. It forms a skin fairly soon, but takes longer to harden fully.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
