Eastry questions
Do you work for landlords with property near Sandwich station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Is Eastry within the area you cover?
Yes. Eastry is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you quote for more than one area?
Yes, we can. More than one area can be quoted together.
Do you take on second-fix sealing for builders?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send the schedule and any specification and we will give you a quote.
Will you just run a new bead over the existing one?
No. The old sealant is cut out fully, the joint cleaned and primed where needed, and a new bead applied.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Is it worth resealing while the house is still settling?
That depends on the joint. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
New build mastic in Eastry, done properly
For builders and developers, we work through plots to the schedule you give us. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover. If you are dealing with untidy sealant flagged on a snagging list and worktop and upstand sealant coming away, we can help, on bathrooms & en suites, plot handovers and kitchens alike.
Homes around Eastry range from older cottages to newer houses, and their floors range just as widely, from timber that moves with the seasons to tiles laid on concrete. Skirting and threshold joints need a sealant that suits the floor.
The work is covered for a year after we finish. If anything is not right with it, call 0345 464 0079 or send us an email.

Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Each joint is cleaned and primed where needed to keep callbacks down.
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We cut out the cracked bead and reseal with a flexible sealant that suits the frame.
When to call us in Eastry
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
Keep an eye out for these signs:
- Messy sealant that spoils new finishes
- Leaking shower tray seals in a new home
- Cracked sealant around new window and door frames
- Cracked caulk along new skirting
In and around Eastry, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What sealant work can’t fix
New sealant cannot fix everything, and we’ll tell you before we start. It will not solve:
- Damaged fittings that need replacing
- Leaking fittings rather than failed sealant
- Settlement cracks that need a surveyor
If in doubt, call 0345 464 0079 or send us an email and we will say what we think before booking.

How the visit works
Every visit runs the same way: we check the joints, protect the area around them, do the work and clear up. Most jobs take a few hours for most snagging lists, longer for a run of plots. In a smaller place like Eastry, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- Tell us about any water getting in
- Let us know about stairs, lifts or work at height
- Tell us about any previous sealing or DIY attempts
How to get a quote
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that is easy.
Related advice
Landlords, agents and businesses in Eastry
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
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 matched to the joint and its conditions, then guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
