Your questions about glazing silicone in Neasden
Can parking be tricky for a visit in Neasden?
Parking in Neasden, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Is Neasden in your area for glazing silicone?
Yes, Neasden is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or send us an email and let us know what needs doing, and we’ll give you a clear price.
Do you replace glass?
Glass replacement is not our trade. We look after the sealant joints and can tell you if a unit seems to have gone.
Can you just put new silicone over the old?
Topping up is a common cause of leaks. A proper job means cutting out, cleaning and resealing.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Where is Mr Mastic based?
We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Do you have insurance?
Yes. We’re fully insured for every job we do.
About our glazing silicone in Neasden
Glazing silicone that has yellowed, blackened or come away looks poor and can leak. It comes off cleanly, without marking the glass before the new bead goes in. If you’re dealing with split or lifting silicone on glass and water tracking down the inner face of the glass, we can put it right, on glass-to-frame joints, shower screens and rooflights alike.
Many London homes are flats, with windows high above the street. Who looks after the outside of the frames can depend on the lease, so check that first.
You are covered for a year from the day we finish. If anything is not right with it, ring 0345 464 0079 or email us.

Can I do it myself?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
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.
What glazing silicone looks like in Neasden
Historic houses like Fenton House (about 2.9 miles east) are a reminder that the area around Neasden 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. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like Northview Junior and Infant School? Then the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Brent Cross West station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

Do you need glazing silicone in Neasden?
Using a sealant not made for glass causes many failures. Some products do not bond well to glass, and acetoxy types can attack some frame materials.
It’s worth asking for a quote if you see:
- A quick top-up bead that didn’t last
- Rooflight joints letting water in
- Stained, discoloured glazing silicone
- Silicone pulling away from the glass
Neasden is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
What your quote should include
- Whether they’re fully insured
- How much experience the applicator has

- When the joint can take water or movement
What affects the cost of glazing silicone
Call for a quick quote. What matters most is:
- Which sealant suits the joint
- Working hours on commercial sites
- The number of rooms or windows
- Mould in or behind the old joints
What you pay reflects the work, not guesswork. That’s why we ask a few questions first.
What we need to know
There’s no need for technical detail. Just tell us:
- Where the job is, and your postcode
- Whether it’s a home or a business
- The problem you’ve noticed
- Roughly how big the job is
Getting a quote is simple: let us know the job and the location and its rough size. Photos by email help us understand the job, and we’ll take it from there.
The process
When we arrive, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. Most jobs take anything from an hour or two to most of a day, depending on the size of the job. For a job in Neasden, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- We find where water is getting in and check whether it’s a sealant joint.
- Old silicone is cut away from the glass and frame without scratching either.
- We clean the joint with a solvent that suits the glass and frame.
- New glazing silicone goes in and is tooled to a neat finish.
- We look over every joint and, where we can, test it with water.
Before we arrive
- Clear the area around the work
- Tell us about any previous sealing or DIY attempts
- Let us know about parking restrictions

For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Why deal with it now?
If the problem is a misted unit or a broken panel, sealant will not help. We say so plainly, so you can call the right trade. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Neasden.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.
