How the visit works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes anything from an hour or two to a full day, depending on how many frames there are, and the area is left clean. For a village or hamlet like Longparish, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about stairs, lifts or work at height
- Tell us about any water getting in

About our window mastic in Longparish
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. We work on aluminium frames, timber windows & doors and composite doors, and the jobs we see most are water coming in at the bottom corners of a door and draughts coming in around windows and doors.
Mastic can only go onto a dry, clean joint, so window work in Longparish is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Each job carries a 12-month guarantee.

Landlords, agents and businesses in Longparish
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Do you need window mastic in Longparish?
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, while a joint packed solid cannot stretch. Backing rod sets the right depth.
The problems people normally mention when they call include:
- Sealant in the wrong colour for the frame
- Untidy mastic left by window fitters
- Mastic that has split away from the wall
- Cracked sealant at the sill ends
Letting a property close to Whitchurch (Hampshire) station? Then renewing tired window mastic between tenants heads off draught and damp complaints.
What your quote should include
- Who does the work, and how experienced they are
- Which sealant they’ll use, and why
- What the quote includes, VAT included or not
- Which colour the sealant will be
When something else is needed
Sealant isn’t the answer to every problem, and we will tell you before work begins. Sealant will not put right:
- Damp coming through the wall itself rather than the frame joint
- Rotten timber, which needs a joiner first
- Draughts through the window seals rather than the frame
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think before you book.

Longparish: your questions answered
Can you help a landlord with a rental near Whitchurch (Hampshire) station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
Is Longparish within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is it messy?
We keep the work tidy. Nearby surfaces are protected.
Will resealing my frames help with draughts?
If the draught is coming in around the frame, yes. If it’s through the window’s own seals or a hinge, that’s a different fix, and we’ll say so.
Are you insured?
Yes. We are fully insured, and we have been doing sealant work for more than 20 years.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
How many windows can you do in a day?
A handful of frames is a short visit. We confirm the timing with your quote.
What window mastic looks like in Longparish
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.
If you look after a building such as Longparish Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as Church of St Nicholas, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How to look after the new joints
So the new joints stay in good condition:
- Keep drainage slots and sill grooves clear
- Look round the frames every year or so
- Keep paint and stain on wooden frames in good order
- Wash the frames with mild soapy water
Most silicone sealants won’t take paint, so if you are planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.

What affects the quote in Longparish
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Working hours on commercial sites
- Whether the work is at height
- The product the joint needs
- The size of the job
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Asking for a quote
There’s no need for technical detail. Just tell us:
- The problem you’ve noticed
- Any previous sealing or DIY work
- How we’d reach the joints
- The address or postcode of the job
Every job is quoted individually. Simply ring 0345 464 0079 or email us and describe the job, and photos are welcome.
Can I do it myself?
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.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
