FAQs for Hartfield
Do you cover smaller places like Hartfield?
Yes. Hartfield 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 help a landlord with a rental near Ashurst Kent station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Is it worth resealing while the house is still settling?
It depends on whether water is getting through. A leaking shower or bath seal should be redone straight away, while small cosmetic gaps can wait a while.
Is it normal for sealant to crack in a new home?
It’s common, and there are normally two reasons: movement as the house dries and settles, and sealant laid onto dust without primer. Cutting it out and resealing properly fixes both.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Is there a guarantee?
Yes. Each job is guaranteed for twelve months.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Do you have insurance?
Yes. Full insurance covers our work.
New build mastic for homes and businesses in Hartfield
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that is reasonable, but a failed shower or bath seal shouldn’t wait. We work on skirting & floors, plot handovers and show homes, and the jobs we see most are cracked caulk along new skirting and sealant that never bonded to the surface.
Work in a small place like Hartfield just needs the journey and access planning, and once on site, the job is the same as anywhere.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

How it works
We bring everything the job needs with us, so you don’t need to buy or prepare anything. Once we have agreed what’s being done, we protect the area and start. It normally takes anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Hartfield, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you are given the cure time.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Mention any leaks or damp you’ve noticed
- Mention any sign-in or site rules at work premises

Advice
Landlords, agents and businesses in Hartfield
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Letting agents and landlords in Hartfield can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Joints and finishes in Hartfield homes
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Aftercare tips
A little care helps the new joints last. We recommend:
- Ventilate bathrooms well, especially in the first year
- Follow the cure time we give you
- Check bath and shower seals every few months as the house settles
- Resist patching a failed seal with a tube from the DIY shop
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents, which can damage the surface.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant and the new finishes intact.
Why it’s worth doing now in Hartfield
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times for the lot. In a small place like Hartfield, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.
