Landlord and commercial work in Gravesend
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
New build mastic for homes and businesses in Gravesend
Snagging sealant properly means taking the failed bead out completely. Fresh silicone can’t bond to the old layer, so it all comes out before we clean, dry and reseal. If you are dealing with smeared, uneven beads picked up at snagging and gaps behind new kitchen upstands, we can help, on windows & doors, plot handovers and skirting & floors alike.
Somewhere as small as Gravesend, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
You get a 12-month guarantee, the same in Gravesend as everywhere else we work.

How the visit works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on the number of plots. Somewhere as small as Gravesend, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Preparing for the visit
- Tell us about any water getting in
- Keep pets and children clear of the area while we work
- Tell us about access, such as stairs, a lift or high-level joints

New build mastic around Gravesend
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 and around Gravesend, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. For new homes near Bishops Stortford station, it’s worth checking the sealant early, while snags are still fresh.

In a small place like Gravesend, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Gravesend questions
Do you work for landlords with property near Bishops Stortford station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
Is Gravesend in your area for new build mastic?
Yes. We work across London and the South East, and Gravesend is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear price.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we’re using and why.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you when we finish.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done.
Is it normal for sealant to crack in a new home?
A new house dries and settles for a year or two, and sealant is often rushed onto dusty, unprimed surfaces. Both lead to early failure.
What colour sealant will you use?
Most bathroom joints are white or clear, but other colours are available. We choose one to suit the room and agree it with you.
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Record problems with dated pictures
- Check bath and shower seals every few months as the house settles
- Avoid scourers and strong chemicals on sealant
- Use the extractor fan every time you shower
Leave the sealant for the cure time we give you before showering or bathing. Silicone is generally left for about a day to cure enough for use.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left in a busy bathroom.
