About our new build mastic in Sibford Gower
We never seal over a failed new-build bead. Fresh silicone can’t bond to the old layer, so it all comes out before we clean, dry and reseal. We work on bathrooms & en suites, kitchens and show homes, and people most often call us about kitchen sealant that has pulled off the wall and sealant work across a run of new homes.
Around Sibford Gower, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Common questions in Sibford Gower
Is Sibford Gower in your area for new build mastic?
Yes, Sibford Gower is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or send us an email and let us know what needs doing.
Is Sibford Gower within the area you cover?
Yes, Sibford Gower is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Will it make a mess?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we’re done.
Do you take out the old sealant first?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
How long before the joint can be used?
Cure times vary by product and the conditions. Before we leave, we will tell you the cure time.
How long does the job take?
That depends on how much there is to do, but most jobs take a few hours for most snagging lists, longer for a run of plots. We will give you a better idea when we quote.
Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Leave it or put it right?
The builder is usually the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Older cottages and farmhouses around Sibford Gower can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will explain what it covers.

Different surfaces, different methods
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.
Plot handovers
Plot mastic is carried out to the developer’s schedule. Joints are prepared properly before sealing to keep callbacks down.
The process
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes a few hours in a single home. In a small place like Sibford Gower, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- Let us know if you’ve seen damp or leaks
- Mention if the joints have been sealed before
- Clear items away from the joints we’re working on
