Sand Mastic in Springvale
Traditional burnt sand mastic around sash and case windows and doors in stone and brick for householders, landlords and businesses in Springvale. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.
- Mastic dropping out of the joint
- A silicone bead on a sash window that spoils the look
- Gaps between timber frames and stone or brick
Sand mastic in Springvale
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. Renewing it closes the gap so the surround looks right again. If you have old cement repairs round a window that have failed and gaps round a timber door in stone or brick, we can put it right, whatever the surface.
In smaller places like Springvale, 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.
Each job carries a 12-month guarantee, large or small.

Why act early in Springvale
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic is the traditional material and finishes neatly against the masonry. Around Springvale, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

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.
If you look after a building such as Kings Worthy Primary School, larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Winchester station, older sash windows in a rental need their mastic kept sound to keep the weather out.

FAQs for Springvale
Can you do sand mastic in Springvale?
Yes, Springvale is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear quote.
Do you cover smaller places like Springvale?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can old silicone round a sash window be swapped for sand mastic?
Yes, it’s a common request. The old silicone has to come out completely so the mastic can sit properly.
Which is right for my windows, sand mastic or modern sealant?
We will talk it through with you. Sand mastic suits many period homes and newer frames suit modern sealant.
How long does the job take?
Most jobs take a few hours for a single window, longer for several. We’ll confirm how long when we quote.
Is the work guaranteed?
Our 12-month guarantee applies to all our work.
Are you insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints, and we clear up when we’re done.
The process
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours per window, depending on the condition of the joints. In a smaller place like Springvale, 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 agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- Try not to wet indoor joints just before the visit
- Plan for the work area to be out of bounds to pets and children
- Tell us about any water getting in

Do you need sand mastic in Springvale?
Shallow joints are a common cause. Mastic that is too thin cracks and drops out, which is why we pack deep voids first and get the depth right.
If you can see any of these, it’s time to have the joints looked at:
- Mastic dropping out of the joint
- Failed mastic on an exposed elevation
- Cement or filler used on old window joints that has cracked
- Gaps between timber frames and stone or brick
In the older streets around St Mary's Church Hall, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Questions to ask before you book
- What the cure time is
- Are they insured?
- How long the guarantee is
- Whether they seal over old material or remove it
