Upper Street homes and the weather
The South East is one of 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 Breamore House (about 0.5 miles north-east) nearby, there’s older building stock in the area around Upper Street as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you look after a building such as Breamore Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s. In the older streets around Church of St Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How we handle sand mastic in Upper Street
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. If you’re dealing with gaps between timber frames and stone or brick and tired mastic found when preparing windows for paint, we can help.
Mastic can only go onto a dry, clean joint, so window work in Upper Street is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
We stand behind the work with a 12-month guarantee.

Why act early in Upper Street
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. Older cottages and farmhouses around Upper Street can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Work for landlords, hotels and businesses
Housing providers, facilities teams and property managers book us too. Several sites can be quoted together, and we are fully insured for the work.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
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 do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

How it works
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from a few hours to a full day, depending on how many windows. In a small place like Upper Street, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose 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.
- We dress the surface so it sits neatly against the masonry.
How to prepare
- Let us know about stairs, lifts or work at height
- Plan for the work area to be out of bounds to pets and children
- Tell us about any previous sealing or DIY attempts

Advice
How we quote for sand mastic
Jobs vary more than people expect. The main factors:
- The number and length of the joints
- Mould in or behind the old joints
- Working hours on commercial sites
- How many areas need sealing
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
Asking for a quote
When you contact us, these details help:
- Photos by email, if that is easy
- What’s wrong with the joints now
- Whether it has been sealed before
- Where the job is, and your postcode
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, phone 0345 464 0079 or send us an email.
When it is not the sealant
It helps to know what we can’t do too:
- Decayed frames that need repair
