Landlord and commercial work in Felpham
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Letting agents and landlords in Felpham can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
How we handle sand mastic in Felpham
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s made from sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. If you have window mastic to renew ahead of painting and cracked mastic round a front door frame, we can help, whatever the surface.
In smaller places like Felpham, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.
A 12-month guarantee comes as standard, so you are covered after we have gone.

When to call us in Felpham
Scraping and sanding before painting can loosen old mastic. Many people find it crumbling when they prepare the windows, which is a good time to renew it.
Most people get in touch when they notice something like this:
- Mastic dropping out of the joint
- Cracked mastic round a front door frame
- Window mastic to renew ahead of painting
- Wind and rain getting in round a sash window
If you look after a building such as Felpham Community College, the mastic around its windows and doors needs looking after like any other building’s.
What to look for in a quote
- How long the guarantee is
- When the joint can take water or movement
- How much experience the applicator has
- Which sealant they’ll use, and why
How the visit works
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a single window, longer for several. For a job in Felpham, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Mention any parking rules near the property
- Tell us about any previous sealing or DIY attempts
- Clear items away from the joints we’re working on

Felpham homes and the weather
Felpham is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to Church of St Mary include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in. For landlords with property near Bognor Regis station, any sash windows need sound mastic to keep draughts and rain out.
Felpham is about 1 mile east of Bognor Regis, in West Sussex. Wherever you are in the PO22 postcode area, we can carry out sand mastic at your property. 371 places in West Sussex are on our list, from the larger towns to small villages. For nearby work, see our Portsmouth page (19 miles or so).
All of PO22 and PO21 is within our area for sand mastic. If you need sand mastic at a property on Sea Road, Ley Road and Limmer Lane or anywhere close by, our applicators can take on the job. If you are just outside Felpham, we cover South Bersted (1 mile west), Flansham (1 mile north-east), Bognor Regis (1 mile west), Middleton-on-Sea (2 miles east) and Shripney (2 miles north-west). Further out, we also cover Worthing (11 miles east), Chichester (6 miles north-west), Selsey (7 miles south-west), Littlehampton (6 miles east), Lancing (15 miles east) and Emsworth (13 miles west).
Near you in Felpham
We work in homes and buildings around The Brooks Local Nature Reserve, The Thatched House and Downview Primary School and the streets around them. Felpham’s nearest station is Bognor Regis station, roughly 1 mile west. A little further out are Bognor Regis Museum (1.2 miles south-west) and Bognor Regis War Memorial Hospital (1 mile west).
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, 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 remove it and do the joint properly, so tell us about it when you ask for a quote.
Different surfaces, different methods
Stone surrounds
Old stone surrounds are often uneven, so the gap is not the same all the way round. Sand mastic is shaped by hand to suit.
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. We renew it the same way as on windows.
Felpham: your questions answered
Will you come out to Felpham?
Yes, Felpham is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Does living near the coast affect sand mastic in Felpham?
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.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Where is Mr Mastic based?
We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
What’s sand mastic made of?
It’s sand mixed with a linseed-oil-based binder for the joint between timber frames and masonry.
Can you match the sealant colour?
Yes. Sealants come in white, clear, grey and other colours for many products, and we agree the colour with you before we start.
What affects the cost of sand mastic
Your quote is based on your job. We look at:
- Mould in or behind the old joints
- How many areas need sealing
- The size of the job
- The type of sealant required
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
What to tell us for a quote
