Glazing silicone for homes and businesses in St Ives

Many conservatory leaks come down to failed sealant, where glass meets frame or frame meets wall. We find the joint that’s letting water in and renew it and tell you plainly if the cause is something else. If you are dealing with water tracking down the inner face of the glass and failed sealant around rooflight glass, we can help.

Outdoor sealant needs dry, clean surfaces, so work on frames around St Ives is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.

All our work is covered by a one-year guarantee.

The number and length of the joints

Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

What to tell us for a quote

Your questions about glazing silicone in St Ives

Do you cover smaller places like St Ives?

Yes, St Ives is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Is glazing silicone in St Ives guaranteed?

Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.

Is it worth trying it myself?

Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Can a conservatory leak be sealed?

In many cases, as long as sealant is the cause. We find where the water gets in first, so you know what you’re paying for.

What information do you need?

Only a few details: the address or postcode, what’s wrong and any access issues. Then call 0345 464 0079 or send us an email.

Where are you based?

Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.

Do you have insurance?

Yes. We’re fully insured.

How long does the job take?

As a guide, most jobs take a few hours for most jobs. Bigger jobs take longer.

Why deal with it now?

Glazing joints need a sealant made for the job. A general-purpose tube may not bond well or may react with the frame, so we use neutral-cure glazing silicone. In a small place like St Ives, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

Should I try it myself first?

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

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 doesn’t work out, we can still put it right.

St Ives homes and the weather

Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Avon Tyrrell House (about 4.5 miles south-east) are a reminder that the area around St Ives 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.

Managing a site like St Ives Primary & Nursery School? Then the mastic around its windows and doors needs looking after like any other building’s.

Looking after it afterwards

Simple care keeps the joints in good condition. We recommend:

Clear the conservatory gutters regularly
Keep harsh solvents off the silicone
Ventilate the conservatory to cut condensation
Don’t use a blade near the sealant

Keep conservatory gutters clear so water does not back up against the seals. Overflowing gutters can cause leaks of their own.

Drips or damp near a glazing joint shouldn’t be ignored. The cause may be sealant or another part and we will find out which.

What we do, step by step

We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from an hour or two to most of a day, depending on the size of the job and we leave things clean and tidy. In a small place like St Ives, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

We look at the glazing and agree which joints need resealing.
We cut away the failed silicone.
We clean and prepare the joint.
New glazing silicone goes in and is finished neatly.
We inspect the work and test it where we can.

Before we arrive

Mention any sign-in or site rules at work premises
Move anything stored near the joints
Plan for the work area to be out of bounds to pets and children
