Lower Pennington questions
Is window mastic in a coastal place like Lower Pennington any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Will you come out to Lower Pennington?
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.
Where are you based?
We work from Crawley. We cover Lower Pennington and the rest of Hampshire, along with the rest of our area.
How many windows can you do in a day?
It depends on access, the old mastic and the size of the frames. We will tell you how long your job needs when we quote.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Can tenants book the work?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
About our window mastic in Lower Pennington
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. If you are dealing with damp patches on the reveal after heavy rain and leaking joints at the ends of sills, we can put it right, on composite doors, patio & French doors and window sills alike.
Mastic can only go onto a dry, clean joint, so window work in Lower Pennington is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
All of our work is guaranteed for twelve months.

What we do, step by step
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a handful of frames, longer for a whole house. Somewhere like Lower Pennington needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- 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.
Getting ready for the visit
- Clear items away from the joints we are working on
- Let us know about stairs, lifts or work at height
- Let us know about earlier repairs to the joints

Advice
Why it’s worth doing now in Lower Pennington
Not every sealant suits a window. Decorators’ caulk and bathroom silicone aren’t designed for outside joints that move. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Where a wall is exposed, as many are in small places like Lower Pennington, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear quote for the lot.
Why book with us
- Quality sealants from Arbo and Everbuild
- White, clear, grey or coloured to suit, where the product allows
- Domestic, commercial and hotel work
- An ARBOMaster approved applicator

Frames and glazing around Lower Pennington
Lower Pennington is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around window and door frames, especially on the side facing the sea. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as Priestlands School, larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Lymington Pier station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Surface by surface
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
Window sills
Masonry sills can have joints where water gets in, including the one between the sill and the frame above. We seal those with a sealant suited to masonry.
What affects the cost of window mastic
We don’t publish a price list. What we look at:
- Any working-time requirements on site
- How many rooms, windows or areas are involved
- Whether the work is at height
- Any mould that needs treating
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll go through it with you.

To help us quote quickly, let us know:
- Access, such as stairs, a lift or height
- What the problem is, such as mould, gaps, leaks or cracking

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 that we can handle for you.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
What we’re called out for in Lower Pennington
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. If the sealant can’t stretch, it splits.
Keep an eye out for any of the following:
- Black, perished sealant on frames
- Hard, cracked sealant around windows
- Rain getting in at the frame or under the sill
- Gaps where the sill meets the wall
In the older streets around Church of All Saints, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What to look for in a quote
- Whether they seal over old material or remove it
- Whether you can choose the colour
- The length of the guarantee
- Whether the sealant suits the joint
