How we handle window mastic in St Ives
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through. If the draught is through the window seals instead, we will tell you. We work on patio & French doors, composite doors and aluminium frames, and people most often call us about gaps where the sill meets the wall and cracked internal joints between frame and plaster.
Mastic can only go onto a dry, clean joint, so window work in St Ives is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Your job is guaranteed for a year, as with all our work.

Windows and doors in St Ives
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Avon Tyrrell House (about 4.5 miles south-east) nearby, there’s older building stock in the area around St Ives 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.
Managing a site like St Ives Primary & Nursery School? Then its window and door frames need their mastic kept sound, just like a home’s. In the older streets around All Saints, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
St Ives is in Hampshire. Across the BH24 area, we cover window mastic for homes and businesses. St Ives is one of 683 towns and villages in Hampshire we cover. We also work in Southampton, around 20 miles away.

How it works
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours for a handful of frames, longer for a whole house. Somewhere like St Ives needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Try not to wet indoor joints just before the visit
- Mention any sign-in or site rules at work premises
- Mention any tricky access

What we can’t put right

- Penetrating damp from a failed cavity tray or render
- Worn gaskets, brush seals or a door that has dropped
If in doubt, call 0345 464 0079 or email us and we’ll say what we think before you book.

For landlords and businesses
Letting agents and landlords in St Ives can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Questions from St Ives
Is St Ives in your area for window mastic?
Yes, St Ives is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or send us an email and tell us what needs doing, and we’ll give you a clear quote.
Do you cover smaller places like St Ives?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can I add another job to the visit?
Of course. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Do you work for hotels and businesses?
Yes. We can plan bigger jobs in stages to suit the site.
Are you insured?
Yes, we’re fully insured for every job we do.
Can you reach windows above the ground floor?
Yes, in most cases. We plan safe access before the job.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
Is the new sealant paintable?
Not if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
Leave it or put it right?
Choosing the product is half the job. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. In a small place like St Ives, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first.

What affects the cost of window mastic
We do not publish a price list. What we look at:
- Any mould that needs treating
- Whether the work is at height
- Whether old sealant or filler has to be cut out
- The number and length of the joints
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. You’ll know the price before we begin.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Pictures of the joints, sent by email
- Whether it’s a home or a business
- If someone has resealed it before
- Where the property is
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we will talk you through the work before giving you a price.
What the job involves on each surface
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. Each is cleaned out and resealed.
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We can talk through the options.
