Lambourn homes and the weather
With historic houses such as Ashdown House (about 3.5 miles north-west) nearby, there’s older building stock in the area around Lambourn as well as newer homes. Where a home is older, 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as Lambourn CofE Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

About our glazing silicone in Lambourn
Frameless shower screens rely on sealant to keep water in. Leaks normally come from the wall joint or the tray joint, and we reseal both. If you have failed sealant around rooflight glass and water tracking down the inner face of the glass, we can put it right, on conservatory frames, glass balustrade bases and glass-to-frame joints alike.
Homes around Lambourn range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Lambourn questions
Will you come out to Lambourn?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What guarantee comes with glazing silicone in Lambourn?
All our work, in Lambourn and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Is it messy?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Lambourn and the rest of West Berkshire, along with the rest of our area.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Do you take out the old sealant first?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Use gentle products around the joints
- Run a squeegee over the glass when you’re done
- Open vents or windows to let moisture out
- Don’t use a blade near the sealant
Keep conservatory gutters clear, so water drains away from the joints. Overflowing gutters can cause leaks of their own.
Damp patches, drips and condensation along a joint are worth checking. The cause may be sealant or another part, and we will tell you which.
The process
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for most jobs. A visit to Lambourn is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- We clean the glass and frame so the new silicone bonds.
- We lay the new bead and tool it smooth.
- Each joint is checked and, where possible, water-tested.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any previous sealing or DIY attempts

Advice
How the job changes by surface
Conservatory frames
Exposed frame joints wear with the weather. A fresh bead seals them again.
Rooflights
Rooflight leaks can come from the sealant or the roof. We check which it is.
How we quote for glazing silicone
Jobs vary more than people expect. What affects the quote:
- The type of sealant required
- How much old sealant there is and how hard it is to remove
- The size of the job
- Working hours on commercial sites
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- Where the property is
- How many joints, rooms or windows are involved
- Whether it has been sealed before
- Whether it’s a home or a business
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. Whenever you’re ready, call 0345 464 0079 or email us.
When to call us in Lambourn
Not every leak is a sealant problem: broken panels, roof problems and blocked gutters can all let water in. That’s why we trace the leak first.
It’s worth asking for a quote if you see:
- Water running down inside the glass
- Stained, discoloured glazing silicone
- Conservatory leaks at frame and glazing joints
- New silicone smeared over old sealant
If you live in an older home near Church of St Michael and All Angels, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What your quote should include
- Who turns up on the day
- What happens if they find a problem under the old sealant
- How the colour is chosen
- Whether they seal over old material or remove it
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
