Gutter sealing in Shermanbury, done properly
Sealant only bonds to a clean, dry joint. That’s why we take out the old sealant and dirt first and the joint is dried before the new sealant goes in. Typical jobs include water dripping where gutter sections meet and open joints in fascias and soffits, across gutter end caps, soffit joints and roofline trims.
Around Shermanbury, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
Our work is backed for twelve months.

Common questions in Shermanbury
What guarantee comes with gutter sealing in Shermanbury?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Is Shermanbury in your area for gutter sealing?
Yes, Shermanbury is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or send us an email and tell us what needs doing.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
Do you install new fascias or gutters?
That’s not something we do. Our work is sealing joints; replacing gutters and fascias needs a gutter or roofline installer.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
How long before the joint can be used?
That depends on the sealant used, so please follow the time we give you when we finish.

Why act early in Shermanbury
A dripping stop end can soak the wall right through the wet months. It’s a small job to put right before the damage spreads. Around Shermanbury, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We’ll give you a clear quote for the lot.

Common problems we fix in Shermanbury
Gutter joints rely on seals that age. Sun and cold make the gutter expand and contract, and old seals crack or slip.
Signs it’s time to call us include:
- Damp on an inside wall under a dripping gutter
- Failed sealant on a garage door frame
- Water running down the wall below the gutter
- Fascia boards with gaps between them
For an older house near a landmark such as The Parish Church of St Giles, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
What your quote should include
- What product goes in the joint
- Is VAT in the price?
- How hidden problems are handled
- Are they insured?
What we cannot put right
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Boards that have decayed or split
- Roof leaks, slipped tiles or failed flashing (a roofer’s job)
- A gutter length that has split
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think before you book.

Advice
What the job involves on each surface
Gutter joints
Gutter joints move and sit in water. A dedicated gutter sealant suits them.
Roofline trims
Roofline trims rely on sealant at their joints. When it splits, water can get behind.
DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
