Landlord and commercial work in Elmer
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
About our sand mastic in Elmer
Across Elmer, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand, finished to suit the masonry. We work on stone surrounds, brick reveals and sash and case windows, and the jobs we see most are mastic worn away on windows facing the weather and patchy fillers round a sash window.
Houses in smaller places like Elmer can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

What sand mastic looks like in Elmer
Elmer 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 is hard on the mastic around older windows and doors, especially on the side facing the sea. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to St Nicholas Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you let a flat or house near Ford station, older sash windows in a rental need their mastic kept sound to keep the weather out. Schools such as Bishop Tufnell CofE Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
Elmer is about 3 miles east of Bognor Regis, in West Sussex. Jobs in Elmer get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee.

Your questions about sand mastic in Elmer
Will you come out to Elmer?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Ford station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or email us with the address and what needs doing, and we’ll send you a clear quote.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Can you match the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
Do you have insurance?
Yes. We’re fully insured, and we have been doing sealant work for more than 20 years.
Can new sealant go over the old?
No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Can you replace silicone on a period window with sand mastic?
In most cases. We remove the silicone and clean the joint before the sand mastic goes in.
Leave it or put it right?
Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad and new mastic seals them. In a smaller place like Elmer, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

What happens on the day
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. It usually takes anything from a few hours to a full day, depending on how many windows. In a smaller place like Elmer, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- 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.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Keep pets and children clear of the area while we work
- Mention any tricky access
Getting a quote
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job.

Looking after it afterwards
So the new joints stay in good condition:
- Find out about consent before window work on a listed home
- Ask us before painting near the mastic
- Don’t run silicone over sand mastic
- Plan mastic work ahead of painting
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
DIY versus a professional finish
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 does not work out, we can still put it right.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
