What we’re called out for in Marshalswick
Using a sealant not made for glass causes many failures. Not every silicone sticks properly to glass, and acetoxy types can attack some frame materials.
People usually contact us after spotting something like this:
- Leaks from the base of a shower screen
- Water getting into a conservatory at the joints
- Drips on the inside of a conservatory window
- Glass-to-glass joints that have split
Homes close to Saint Mary's include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Glazing silicone in Marshalswick
We do not replace glass, and misting between panes means a failed sealed unit. What we do is the silicone around the glass and that’s often where the water gets in. Typical jobs include water tracking down the inner face of the glass and rooflight joints letting water in, on shower screens, glass-to-frame joints and glass balustrade bases.
Homes around Marshalswick 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.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

What glazing silicone looks like in Marshalswick
With historic houses such as Batchwood Hall (about 2 miles west) nearby, there’s older building stock in the area around Marshalswick as well as newer homes. 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For landlords with property near St Albans station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. Schools such as St John Fisher Roman Catholic Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Leave it or put it right?
Resealing can’t fix a failed unit or a cracked panel. We will tell you that rather than seal it anyway, so you can call the right trade. In a smaller place like Marshalswick, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
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. The price is agreed before we begin.

FAQs for Marshalswick
Will you come out to Marshalswick?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
Will there be a smell?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
Do you work for landlords and businesses?
Yes, often. We can quote for several properties at once, and between tenancies is a good time for the work.
Can you fix a leaking conservatory?
In many cases, as long as sealant is the cause. We find where the water gets in first before any sealing.
How long does the job take?
Most jobs take anything from an hour or two to most of a day, depending on the size of the job, including the preparation. Your quote will say how long we expect yours to take.
I’m a tenant. Can you help?
Yes. Check with your landlord; we can send the quote to them too.
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.

The process
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours for most jobs and we leave things clean and tidy. For a job in Marshalswick, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by finding the leak and making sure sealant is the cause.
- 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.
- We apply a neutral-cure glazing silicone and tool it smooth.
- We look over every joint and, where we can, test it with water.
How to prepare
- Clear the area around the work
- Plan for the work area to be out of bounds to pets and children
- Tell us about any water getting in
Ask for a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email pictures if that is easy.
Advice
How to look after the new joints
So the new joints stay in good condition:
- Stick to mild cleaners on glass
- Squeegee the shower screen after each use
- Do not leave a drip for the next storm
- Use gentle products around the joints
On shower screens, wipe or squeegee after use and keep the room ventilated. It helps stop mould getting into the silicone.
Act on black or lifting silicone early. Once it starts to peel, water gets behind it and the leak gets worse.
