Sand mastic for homes and businesses in Newbury Park
Silicone on a period window often looks wrong and isn’t always the right material. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. Typical jobs include mastic that needs renewing before redecorating and weathered mastic on the most exposed windows, across tenement windows, sash and case windows and stone surrounds.
London has a lot of flats and conversions, where windows are often on upper floors. In a converted house or block, the lease generally says who is responsible for the windows, so it’s worth checking before booking.
We stand behind the work with a 12-month guarantee.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

How we quote for sand mastic
Your quote is based on your job. We take into account:
- Whether the work is at height
- Which sealant suits the joint
- When we can work, for business premises
- Mould in or behind the old joints
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Whether it has been sealed before
- The rough size of the job
- Access, such as stairs, a lift or height
- What’s wrong with the joints now
We quote each job on its own, so start by telling us what you need. Just call 0345 464 0079 or email us with the details.
What happens on the day
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to a full day, depending on how many windows. In a London area like Newbury Park, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Before we arrive
- Try not to wet indoor joints just before the visit
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work
How to get a quote
Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we’ll take it from there.
Advice
When to call us in Newbury Park
Age is the main cause. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
Most people get in touch after spotting something like this:
- Mastic dropping out of the joint
- Patchy fillers round a sash window
- Gaps between timber frames and stone or brick
- Wind and rain getting in round a sash window
Newbury Park is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
Before you book anyone
- When the joint can take water or movement
- Is the old sealant removed completely?
- How much experience the applicator has
- How the colour is chosen
Newbury Park homes and the weather
Historic houses like Valentines Mansion (about 0.9 miles west) are a reminder that the area around Newbury Park 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 a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking.
Homes close to Saint Laurence Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. Letting a property close to Seven Kings station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.
