Gravesend: your questions answered
I let a flat near Gravesend station. Can you help?
Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. You can ring 0345 464 0079 or email us with the details for a clear quote.
Does living near the coast affect gutter sealing in Gravesend?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Can you do several jobs on one visit?
Yes. More than one area can go on one quote.
Is sealing fascia joints something you do?
Yes, often alongside gutter joints. The gaps are cleaned and sealed neatly.
How long before the joint can be used?
Cure times vary by product. Before we leave, we will tell you the cure time.
How we handle gutter sealing in Gravesend
Our work covers gutter joints and end caps as well as fascias and soffits, along with roofline trims and garage door frames. It’s joint work rather than new guttering. We work on gutter joints, garage door frames and soffit joints, and people most often call us about end caps that drip every time it rains and wet patches on the wall under a gutter joint.
Around Gravesend, outside jobs take in garage door frames, porches, gutters and trims as well as walls. Each joint between different materials moves in its own way, so the sealant has to cope with that.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

The process
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours, depending on the number of joints and the access. For a job in Gravesend, we need access to where the work is and somewhere nearby to park. For outside work, let us know about side access, gates and any upper-floor joints.
- We look at the gutters, fascias and trims and agree the joints to seal.
- Each joint is cleaned and any old sealant removed.
- We make sure everything is dry.
- We apply exterior or gutter sealant and finish it neatly.
- The joints are checked once sealed.
How to prepare
- Move anything stored near the joints
- Mention any leaks or damp you’ve noticed
- Plan for the work area to be out of bounds to pets and children

Walls and rooflines in Gravesend
Gravesend is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on gutter, fascia and roofline joints, which can dry out and crack sooner where a building faces the weather. Historic houses like Cobham College (about 2.9 miles south) are a reminder that the area around Gravesend has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
In the older streets around Christ Church Milton, old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you let a flat or house near Gravesend station, leaking gutter joints on a rental are best caught before they stain the walls. If you look after a building such as Whitehill Primary School, its movement joints, gutters and trims need looking after like any other building’s.

Different surfaces, different methods
Gutter joints
A dripping joint doesn’t always mean a failed gutter. Sealing the joint often stops it.
Garage door frames
Failed sealant around a garage door frame lets water in. We cut it out and reseal.
How we quote for gutter sealing
You’ll get a clear quote before we start. It takes into account:
- The number of rooms or windows
- The type of sealant required
- The old material and how stubborn it is
- The number and length of the joints
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, call 0345 464 0079 or email us and we’ll give you an honest view and a quote.
Helping us quote
What to tell us when you ask for a quote:
- What the problem is, such as mould, gaps, leaks or cracking
- Where the job is, and your postcode
- If someone has resealed it before
- A few pictures by email, if you can
For gutter sealing in Gravesend, phone 0345 464 0079 or email us. Tell us what the problem is and where, and we will agree the price before any work begins.
What happens if it’s left?
Water from a leaking joint hits the same spot every time. Left, it can stain walls and lead to damp so early sealing is worthwhile. In a family home in Gravesend, a failed seal around a bath or a frame lets water into places you can’t see, like the floor under a bath, the back of a panel or the inside of a wall. Left alone, that means rot, damp and a bigger repair.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Aftercare tips
To keep the joints looking good and working properly:
- Keep an eye out for wet patches below a joint
- Get a dropping gutter looked at quickly
- Keep downpipes clear
- Rest ladders on the wall, not the gutter
Have a look at the gutter during a downpour now and then. It’s the easiest time to see a leak.
Split sealant on fascias and trims lets water in behind. Sealing it early keeps the boards behind dry.
