Common questions in Upper Horsebridge
Do you work for landlords with property near Polegate station?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
Is Upper Horsebridge within the area you cover?
Yes. Upper Horsebridge is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is it normal for sealant to crack in a new home?
Lots of new homes see sealant crack early as timber and plaster dry out. Rushed application on dusty surfaces makes it worse.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll explain our choice.
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.
Is the work guaranteed?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we will put it right.
When is the best time to reseal in a new build?
If the seal has failed and water is getting in, do it now. Hairline cosmetic gaps can wait until the house has settled.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
About our new build mastic in Upper Horsebridge
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. Common call-outs are for second-fix sealing on new plots and cracked caulk along new skirting, on windows & doors, bathrooms & en suites and kitchens.
If you’ve bought a new home in or near Upper Horsebridge, the first year or two is a good time to check the sealant. Common snags include open skirting joints, lifting shower seals and gaps around frames.
Each job carries a 12-month guarantee, large or small.

How the visit works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. It usually takes anything from a few hours to several days, depending on the number of plots. A visit to Upper Horsebridge is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Before we arrive
- Try not to wet indoor joints just before the visit
- Let us know about stairs, lifts or work at height
- Keep children and pets away from the work area

Advice
Landlords, agents and businesses in Upper Horsebridge
We work for letting agents and landlords as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
What sealant work can’t fix
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- Settlement cracks that need a surveyor
- Baths and trays that move too much for sealant to cope with
- Deciding who is responsible under a builder’s warranty
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly.

New homes and floors in Upper Horsebridge

When to call us in Upper Horsebridge
When the heating goes on in the first winter, the house dries fast. Gaps open along skirting, frames and worktops and cracks appear in the sealant.
These are the problems we are asked about most:
- Kitchen sealant that has pulled off the wall
- Leaking shower tray seals in a new home
- Cracked caulk along new skirting
- Messy sealant that spoils new finishes
Around Upper Horsebridge, as everywhere, new build mastic is only as good as the preparation behind it.

How we quote for new build mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- Any mould that needs treating
- How many rooms, windows or areas are involved
- How much old sealant there is and how hard it is to remove
- The product the joint needs
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
What to tell us for a quote
Before you ask for a quote, have a think about:
- A few pictures by email, if you can
- Where the property is
- The type of property
- Any previous sealing or DIY work
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we’ll talk you through the work.
Should I try it myself first?
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, then guaranteed for a year.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

What else we do in Upper Horsebridge
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Open a window or run the fan after bathing
- Wipe joints with warm soapy water
- Do not seal over failed sealant yourself
- Put sealant faults on your snagging list early
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and protects the rest of the house.
