Glazing silicone in Horncastle, done properly
Many conservatory leaks come down to failed sealant at the glass-to-frame or frame-to-wall joints. We trace the leak to the joint and reseal it, and if it’s something sealant can’t fix, we will tell you. Typical jobs include water escaping where a screen meets the wall and split or lifting silicone on glass, across glass-to-frame joints, glass balustrade bases and glass-to-glass joints.
In a smaller place like Horncastle, some walls face open ground and catch the full force of the weather. The mastic around frames on those walls tends to age faster.
Every job is covered by a 12-month guarantee.

What affects the cost of glazing silicone
We do not publish a price list. What we look at:
- The number of rooms or windows
- The number and length of the joints
- Any working-time requirements on site
- How easy the joints are to reach
The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before work begins, so you know where you stand.
Asking for a quote
When you call or email, it’s useful to know:
- Where the job is, and your postcode
- Pictures of the joints, sent by email
- Roughly how big the job is
- If it’s domestic, commercial or a hotel
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
FAQs for Horncastle
Do you work for landlords with property near Reading West station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll send you a clear quote.
Can you do glazing silicone in Horncastle?
Yes. Our work covers London and the South East, and Horncastle is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you.
Are you fully insured?
Yes. We are fully insured for every job we do.
Can you just put new silicone over the old?
New silicone will not bond to old silicone and water gets between the layers. The old bead always comes out first.
How long will you be here?
A typical job takes anything from an hour or two to most of a day, depending on the size of the job, including the preparation. We will confirm how long when we quote.
Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
Is a special sealant needed for glass?
We pick a glazing silicone to suit the materials. Neutral-cure silicone is the usual choice, as some acetoxy types can attack certain metals.
Aftercare tips
So the new joints stay in good condition:
- Stick to mild cleaners on glass
- Check the gutters above the glazing for debris
- Squeegee the shower screen after each use
- Avoid scraping close to the bead
Use mild cleaners on and around the silicone. Strong solvents can soften or mark it.
Shower screen leaks can go unnoticed. Water can soak into the floor or reach the room below before you spot it.
When something else is needed
A few problems are outside what sealant work can do:
- Rotten or badly damaged frames
- Condensation trapped between two panes
- Water coming through the roof rather than a sealant joint
If you’re not sure, just phone 0345 464 0079 or email us and we will give you a straight answer.
Joints and surfaces we work on
- Shower screens
- Glass balustrade bases
- Glass-to-frame joints
- Rooflights
- Glass-to-glass joints
- Conservatory frames
When to call us in Horncastle
New silicone over old silicone will not bond. Plenty of leaks come from a quick top-up over the old bead leaving a path for water.
Keep an eye out for any of the following:
- Water running down inside the glass
- Shower screens leaking along the wall or tray
- Split or lifting silicone on glass
- Rooflight joints letting water in
If you live in an older home near Church of St Michael, the joint between an old wall and a newer frame is generally the first place rain gets in.
Questions to ask before booking
- Who does the work, and how experienced they are
- What the quote includes, VAT included or not
- What happens if the job turns out different
- Which sealant they’ll use, and why
What we do, step by step
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours, depending on how many joints need doing. A visit to Horncastle 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.
- The joint is cleaned and degreased.
- We lay the new bead and tool it smooth.
- We check the finished joints and test with water where it’s safe.
Getting ready for the visit
- Move anything stored near the joints
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any water getting in

Windows and doors in Horncastle
With historic houses such as Mapledurham House (about 2.8 miles north) nearby, there’s older building stock in the area around Horncastle as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Reading West station change hands often, and glazing joints are worth checking at the end of a tenancy, before a small leak grows. Managing a site like Kennet Valley Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

Why deal with it now?
If the problem is a misted unit or a broken panel, sealant won’t help. We say so plainly, so you can call the right trade. Homes in smaller places like Horncastle can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you’re 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 does not work out, we can still put it right.
