Sand mastic in East Wellow, done properly
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. We work on tenement windows, sash and case windows and brick reveals, and common reasons people get in touch are mastic dropping out of the joint and cement or filler used on old window joints that has cracked.
Outdoor sealant needs dry, clean surfaces, so work on frames around East Wellow is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
Every job comes with our 12-month guarantee.

Why act early in East Wellow
Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. Older cottages and farmhouses around East Wellow can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.

How the visit works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take a few hours for a single window, longer for several. In a small place like East Wellow, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any sign-in or site rules at work premises
- Tell us if parking is tricky

When something else is needed
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Cracked or broken glass
- Decayed frames that need repair
- Whether work needs listed building consent
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly before booking.
What we seal
- Sash and case windows
- Brick reveals
- Period & listed homes
- Tenement windows
- Timber door frames
- Stone surrounds
Different surfaces, different methods
Brick reveals
An open joint at a brick reveal lets weather in. New mastic seals the gap.
Period and listed homes
Period homes look their best with traditional materials.
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Do not run silicone over sand mastic
- Plan mastic work ahead of painting
- Take care around the mastic when scraping paint
- Leave the new mastic unpainted
Leave the new mastic unpainted, as traditional guidance advises. If you are redecorating, ask us first.
Sound mastic protects the frame. Failed mastic lets water reach the timber and timber that stays wet can rot.
For landlords and businesses
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
We work for landlords and letting agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.

What is sand mastic?
Sand mastic is a traditional material for pointing round windows and doors. It combines sand with a linseed-oil-based binder.
Can you match the sealant colour?
We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.
How much does sand mastic cost in East Wellow?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before work begins.
Is sand mastic better than silicone for my windows?
For period timber windows in stone or brick, sand mastic is often the better fit. On modern frames, we’d normally use a flexible sealant.
What guarantee comes with the work?
There’s a 12-month guarantee on every job.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Windows and doors in East Wellow
Historic houses like Landford Manor (about 2.8 miles west) are a reminder that the area around East Wellow has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. 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 live in an older home near Church of St Margaret, the joint between an old wall and a newer frame is normally the first place rain gets in. For landlords with property near Romsey station, any sash windows need sound mastic to keep draughts and rain out. If you look after a building such as Wellow School, its window and door frames need their mastic kept sound, just like a home’s.

What affects the quote in East Wellow
Some jobs are bigger than they look, and some smaller. The main factors:
- The size of the job
- Whether old sealant or filler has to be cut out
- Whether the work is at height
- Mould in or behind the old joints
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.
