What affects the quote in Doleham
Every job gets its own quote. These are the things that affect it:
- How easy the joints are to reach
- Working hours on commercial sites
- Whether old sealant or filler has to be cut out
- The product the joint needs
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start.
What we need to know
There’s no need for technical detail. Just tell us:
- Any access issues, like height or stairs
- A few photos by email, if you can
- The address or postcode of the job
- The rough size of the job
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. Whenever you’re ready, phone 0345 464 0079 or drop us an email.
How we handle new build mastic in Doleham
Across Doleham, we work for both new-home owners and the builders handing those homes over. Whether it’s one en suite or a run of plots, the method is the same: remove, clean, prime where needed, then a neat new bead. We work on bathrooms & en suites, show homes and windows & doors, and the jobs we see most are shower seals failing in the first year or two and gaps opening as the house dries out and settles.
Work in a small place like Doleham just needs the journey and access planning, and once on site, the job is the same as anywhere.
There’s a 12-month guarantee on every job.

Plot handovers
Good preparation at handover saves snagging later. We clean out building dust before sealing and prime where the product needs it.
Show homes
We can refresh show-home sealant that has discoloured or been knocked. The old bead comes out and a clean new one goes in.
Doleham questions
I let a flat near Doleham station. Can you help?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Is Doleham within the area you cover?
Yes. Doleham is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Where do you work from?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Should I go to my builder first?
Report it to the builder first while you’re covered. Once that’s done, or if they will not put it right, we can reseal it properly.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
Is there a guarantee?
Yes. Every job comes with our 12-month guarantee.
What sealant work cannot fix
New sealant cannot fix everything, and we will tell you before we start. It will not solve:
- Leaks from pipes, valves or wastes, which need a plumber
- Settlement cracks that need a surveyor
- Deciding who is responsible under a builder’s warranty
If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer.
Surfaces we seal

How it works
On the day, we start by going over the job with you. Surfaces next to the work are protected before we start. Most jobs take a few hours for most snagging lists, longer for a run of plots. Somewhere as small as Doleham, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- On commercial sites, let us know about site rules
- Mention if the joints have been sealed before

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Use the extractor fan every time you shower
- Watch for new gaps as the house dries out
- Wipe joints with warm soapy water
- Avoid running a DIY bead over the old one
Leave the sealant for the cure time we give you before showering or bathing. Silicone is normally left for about a day.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant and the new finishes intact.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
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.
Why deal with it now?
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or is not dealt with, we can reseal it properly. Around Doleham, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first.
