What affects the quote in Elson
The quote reflects the job in front of us. We look at:
- Mould in or behind the old joints
- How easy the joints are to reach
- How much there is to do
- How many rooms, windows or areas are involved
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, phone 0345 464 0079 or send us an email and we will give you an honest view and a quote.

- Any previous sealing or DIY work
- The rough size of the job
- How we’d reach the joints
- What’s wrong with the joints now
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we’ll explain what’s involved.
Sand mastic for homes and businesses in Elson
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. Typical jobs include window mastic to renew ahead of painting and gaps round a timber door in stone or brick, across timber door frames, brick reveals and tenement windows.
Around Elson, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Should I try it myself first?
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. All the old material has to come out first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
How the visit works
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours for a single window, longer for several, depending on the size of the job. For a job in Elson, 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 agree which joints need doing.
- 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.
- The surface is finished to suit the stone or brick.
Before we arrive
- Mention any parking rules near the property
- Mention any leaks or damp you’ve noticed
- Move anything stored near the joints

Advice
Sand mastic in Elson: local notes
Elson is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around Church of St Thomas, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Portsmouth Harbour station, any sash windows need sound mastic to keep draughts and rain out. For site and facilities teams at buildings such as Elson Infant School, larger buildings have plenty of frames, and the mastic around each one ages.

What’s near Elson
In Elson, that means homes and buildings near The Kings Head pub, St Vincent College and Brune Park Community School. The nearest railway station is Portsmouth Harbour station, roughly 2.1 miles south-east of the centre. Well-known places in the area include Search (1.6 miles south-east) and Portchester Castle (2.2 miles north-east). The countryside around Elson includes West of the River Alver and Portsdown Hill.
What the job involves on each surface
Timber door frames
Doors face weather and wear and the mastic can crack early. We rake it out and renew it.
Period and listed homes
A traditional finish suits a period property.
Why deal with it now?
Not every draught comes from the sashes themselves. Open mastic joints round the box can let air in and new mastic seals them. In an older home around Elson, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
Combining jobs into one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

FAQs for Elson
Is sand mastic in a coastal place like Elson any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Can you help a landlord with a rental near Portsmouth Harbour station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
How long does sand mastic take?
As a guide, most jobs take anything from a few hours to a full day, depending on how many windows. Larger jobs naturally take longer, and we will say how long yours will take.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you offer different sealant colours?
Most of the time, yes. We will explain which colours are available and agree one before we start.
How long does sand mastic take to harden?
It forms a skin fairly soon and it hardens fully over a longer time. Timing depends on the weather and the joint.
Do you have insurance?
Yes. We are fully insured.
