Liphook Window Mastic
Problem with your window and door frames in Liphook? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Rushed sealant from a window installation
- Cracked or shrunken mastic around the frame
- Damp patches on the reveal after heavy rain
How it works
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the work takes anything from an hour or two to a full day, depending on how many frames there are for a typical job. In a smaller place like Liphook, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- 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, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Tell us if parking is tricky
- Clear the area around the work

Advice
Window mastic in Liphook, done properly
Whether it’s one leaking patio door or every frame on the house, you will get a clear quote before any work starts. To get one, call 0345 464 0079 or send us an email with the number of frames and any access details for window mastic in Liphook. If you are dealing with whistling draughts around closed windows and black, perished sealant on frames, we can put it right.
In a smaller place like Liphook, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. That is hard on the mastic around frames and sills.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Aftercare tips
Aftercare is simple:
- Wash the frames with mild soapy water
- Keep drainage slots and sill grooves clear
- Keep solvents and bleach off the sealant
- Keep paint off silicone joints
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.

Common questions in Liphook
I let a flat near Liphook station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Do you cover smaller places like Liphook?
Yes, Liphook 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.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
How do I get a quote for window mastic in Liphook?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.

Yes. We are fully insured.

Windows and doors in Liphook
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.
If you let a flat or house near Liphook station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. For an older house near a landmark such as St Mary's Church Centre, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Liphook is about 8 miles north-east of Petersfield, in Hampshire. Liphook gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. Across Hampshire, we cover 683 places, Liphook among them. You can also see our page for Portsmouth, about 22 miles away.
Work in GU30 is quoted and booked the same way as anywhere else. Window mastic is available to properties on London Road, Station Road and Childerstone Close.

Local landmarks in Liphook
In Liphook, that means homes and buildings near The Green Dragon Public House and Liphook Infant School and the streets around them. The nearest railway station is Liphook station, roughly 0.5 miles south of the centre. A little further out are Chase Community Hospital (3.3 miles north-west). For a walk, there’s Lynchmere Commons and Wheeler's Down.
What we are called out for in Liphook
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. If the sealant can’t stretch, it splits.
It’s worth asking for a quote if you see:
- Cold air getting in at the frame edge
- White mastic on grey or black frames
- Leaking joints at the ends of sills
- Gaps between the frame and the inside reveal
Schools such as Bohunt School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
What to look for in a quote
- Whether they’re fully insured
- How much experience the applicator has
- Whether VAT is included
- Which colour the sealant will be
Leave it or put it right?
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. Homes in smaller places like Liphook 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.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.
