What happens on the day
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes anything from a few hours to several days, depending on the number of plots. Parking around Hawley is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Mention any tricky access
- Mention any parking rules near the property

Related advice
New build mastic in Hawley
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. If you’re still within the builder’s snagging or warranty period, tell them first and if that stalls, we can do it. We work on skirting & floors, bathrooms & en suites and show homes, and the jobs we see most are sealant that never bonded to the surface and joints pulling apart as timber shrinks.
Where new homes go up in smaller places like Hawley, it’s often a small development or a single plot. Each still needs its sealant and floor joints finished properly from day one.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
How we quote for new build mastic
Your quote is based on your job. We look at:
- The type of sealant required
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
- The size of the job
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Helping us quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Photos by email, if that’s easy
- Access, such as stairs, a lift or height
- The type of property
- The rough size of the job

What sealant work can’t fix
New sealant cannot fix everything, and we’ll tell you before we start. Sealant won’t put right:
- Structural cracks in walls or ceilings
- Disputes or warranty claims with your builder
- Plumbing faults behind the sealant
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.

When to call us in Hawley
Fresh sealant can be knocked or cut by trades finishing off. A bead disturbed before it has cured may never seal properly and it shows once the home is in use.
Any of these means the joints need attention:
- New-build shower sealant that has already split
- Frame joints opening as the plaster dries
- Worktop and upstand sealant coming away
- Skirting joints opening in the first winter
For new homes near Blackwater station, it’s worth checking the sealant early, while snags are still fresh.
Before you book anyone
- How long the guarantee is
- Who turns up on the day
- When the joint can take water or movement
- Is VAT in the price?
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Watch for new gaps as the house dries out
- Photograph failed sealant before it’s redone
- Wait for the cure time before using a resealed shower
- Get a leaking seal dealt with straight away
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.

Why act early in Hawley
Small cosmetic gaps can wait for the house to settle, but a leaking seal cannot. If you’re unsure which you have, phone 0345 464 0079 or drop us an email with photos and we will tell you. Homes in smaller places like Hawley can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Ask us for a quote and we will explain what it covers.
