Aspley Guise: your questions answered
Do you work for landlords with property near Aspley Guise station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can phone 0345 464 0079 or email us with the details for a clear quote.
Will you come out to Aspley Guise?
Yes. Aspley Guise is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Is consent needed for window work on a listed home?
Speak to your local planning authority before work starts. Sand mastic is often favoured as like for like but the decision is theirs.
Is it messy?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Can sand mastic be painted?
It’s traditionally left unpainted, which is what traditional guidance recommends. Talk to us before any painting near it.
When will the new mastic be hard?
It forms a skin fairly soon and it hardens fully over a longer time. Timing depends on the weather and the joint.
How we handle sand mastic in Aspley Guise
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant and we’ll explain which is best for yours. If you have failed mastic on an exposed elevation and a silicone bead on a sash window that spoils the look, we can help, whatever the surface.
Around Aspley Guise, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
You are covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or drop us an email.

Quotes for sand mastic in Aspley Guise
Some jobs are bigger than they look, and some smaller. The main factors:
- Which sealant suits the joint
- Whether the work is at height
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
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 will know the price before we begin.

What sand mastic looks like in Aspley Guise
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Woburn Abbey (about 2.5 miles south-east) nearby, there’s older building stock in the area around Aspley Guise as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Rented homes near Aspley Guise station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. In the older streets around Church of St Botolph, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Different surfaces, different methods
Stone surrounds
We take care not to mark the stone when the old mastic comes out.
Period and listed homes
A traditional finish suits a period property, and sand mastic is one of them.
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Don’t paint over the new mastic
- Have rotten timber repaired before new mastic goes in
- Check the mastic when you check the paintwork
- Keep modern sealant off the mastic
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. Paint over cracked mastic only covers it up.
