Window mastic for homes and businesses in Hookwood
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. If you have hard, cracked sealant around windows and whistling draughts around closed windows, we can help, on window sills, patio & French doors and uPVC windows alike.
Mastic can only go onto a dry, clean joint, so window work in Hookwood is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
A 12-month guarantee comes as standard.

Hookwood homes and the weather
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around Church of St Bartholomew, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For landlords with property near Horley station, renewing tired window mastic between tenants heads off draught and damp complaints.
Hookwood is about 1 mile south-west of Horley, in Surrey. Hookwood gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a one-year guarantee. Across Surrey, we cover 395 places, and Hookwood is one of them.
Postcode districts we cover here for window mastic: RH6. If you need window mastic at a property on Campbell Close, Mistley Gardens and Kennel Lane or a nearby road, we can help.

FAQs for Hookwood
Do you work for landlords with property near Horley station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Is Hookwood in your area for window mastic?
Yes, Hookwood 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 tell us what needs doing, and we’ll give you a clear price.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
How long does it take to reseal the windows on a house?
Allow a few hours for a handful of frames, longer for a whole house. Access and the amount of old mastic make the biggest difference.
Can you do several jobs on one visit?
Of course. Doing several areas at once is usually more efficient.
Does the work come with a guarantee?
Yes. Each job is covered for 12 months, inside or out.
What affects the quote in Hookwood
You’ll get a clear quote before we start. It takes into account:
- Whether the work is at height
- The amount of work
- The product the joint needs
- Any mould that needs treating
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.
What to tell us for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- What’s wrong with the joints now
- How many joints, rooms or windows are involved
- Any access issues, like height or stairs
- If someone has resealed it before

Leave it or put it right?
Resealing frames is a short job: it takes most of a day for a typical house, less for a few frames. Wait for damp to appear and there may be plaster and decorating to sort out too. Older cottages and farmhouses around Hookwood can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

What we’re called out for in Hookwood
Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. When that sealant fails, water gets into the wall or under the frame.
Common reasons people contact us are:
- Rushed sealant from a window installation
- Hard, cracked sealant around windows
- Draughts coming in around windows and doors
- Cracked internal joints between frame and plaster
Schools such as Manorfield Primary and Nursery School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

How the visit works
On the day, we look over the joints with you first. Surfaces next to the work are protected before any work begins. Most jobs take a morning for a couple of windows and a door. In a small place like Hookwood, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Mention any parking rules near the property
- For business premises, tell us about site rules or sign-in

We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
If you manage several properties in or around Hookwood, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs, and photos by email help.
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
