Sand mastic in Albany Park, done properly
We renew sand mastic around sash windows and doors set in stone or brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. If you’re dealing with draughty sash windows at the surround and crumbling sand mastic round a window, we can put it right, whatever the surface.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. Over the years, the sealant around them shrinks, cracks and pulls away, letting in draughts and water.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or send us an email.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

What else we do in Albany Park
What affects the cost of sand mastic
We quote each job individually. These are the things that affect it:
- The product the joint needs
- The number and length of the joints
- Whether old sealant or filler has to be cut out
- How many rooms, windows or areas are involved
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, ring 0345 464 0079 or send us an email for an honest opinion and a quote.
Helping us quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Whether it’s a home or a business
- Where the job is, and your postcode
- Any access issues, like height or stairs
- The rough size of the job
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that is easy.
Why act early in Albany Park
New mastic over crumbling mastic won’t hold. Raking out and preparing the joint gives it a sound base so the new work lasts. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

FAQs for Albany Park
Is parking an issue for sand mastic in Albany Park?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Is Albany Park in your area for sand mastic?
Yes. Our work covers London and the South East, and Albany Park is part of that. You can call 0345 464 0079 or send us an email and let us know what needs doing, and we will give you a clear quote.
Can you match the sealant colour?
We’ll suggest a colour to suit the surroundings. The product needed can limit the range.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we are using.
Is it possible to take out silicone and use sand mastic instead?
Yes. We remove the silicone and clean the joint before the sand mastic goes in.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Can I add another job to the visit?
Yes. Just list everything you need.
What guarantee comes with the work?
All our work has a one-year guarantee, and we are fully insured.
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Go gently near the mastic when preparing windows
- Look over the window mastic once a year
- Find out about consent before window work on a listed home
- Get any rot dealt with first
Leave the new mastic unpainted, which is the traditional advice. If you are redecorating, ask us first.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
What happens on the day
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself generally takes a few hours for a single window, longer for several, depending on the size of the job. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- Each surround is checked first.
- The joint is raked out and cleaned.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
How to prepare
- Move anything stored near the joints
- Mention any sign-in or site rules at work premises
- Tell us about any water getting in
