What affects the price in Dundonald
There are no hourly rates or hidden extras. The price is based on:
- Any earlier repairs that need removing first
- Doing more than one item at once
- Whether it’s a chip, crack, burn or wear
- Unusual colours or finishes
A repair usually costs much less than people expect, especially compared with replacing and refitting. Photos let us give you the exact figure.
Quotes from your pictures
Most quotes are done from pictures alone. To make it quick:
- The postcode, so we can plan the visit
- Daylight if possible, and no flash reflection
- A wider photo showing the whole bath or shower
- What it’s made of, if you know
A quote takes minutes to ask for: take one close-up and one wider shot of the bath or shower, add your postcode and send them over. What comes back is a fixed quote, not a guess.
FAQs for Dundonald
Will the price change on the day?
We’ll show you and explain before doing anything extra. You won’t be charged for anything you haven’t agreed.
What areas do you cover?
Everywhere in the UK, Dundonald included. There is no extra charge for travel.
Can you quote from pictures?
Yes, almost always. A close-up and a wider photo are enough to give a fixed price.
Is my repair covered?
Yes, for a year. If there’s a problem with the work in that time, we come back and put it right.
I rent my home. Can I book you?
We can work for tenants, landlords or agents. Just ensure the landlord agrees.
Do you cover Dundonald?
Yes, we do. We send a technician to Dundonald for every job, and the price is the same as everywhere else.
Do you do work for letting agents?
Yes, often. We can quote for several properties together and work between tenancies.
Is a repair better than a new one?
In most cases, yes. Replacement brings removal, refitting and making good, which a repair avoids. If it isn’t worth repairing, we will tell you.
Why it’s worth resealing in Dundonald
Resealing costs very little. Failed sealant can lead to water damage that is much more expensive. No two jobs are quite the same, so each one is priced on its own. What’s damaged, how badly and how easy it is to reach all play a part, and doing several things on one visit costs less than separate visits.
Why us?
- CHAS and Constructionline accredited
- One price list for the whole UK
- No need to remove anything
- Most jobs done in one visit

Rental properties take more wear, and replacing items every time a tenant leaves is expensive. Repairing between tenants keeps the property presentable for less.
Can I fix it myself?
We understand the appeal of fixing it yourself. The risk is that a kit repair hides the damage for a while, then fails, and the old filler has to come out before a proper repair.
If you’ve already tried a DIY fix, that is fine. We remove the old filler and start again, so it will not stop us repairing it. Just mention it when you send pictures, as it can add time.
How it works
We turn up when we said we would and looks over the damage before anything else. The floor and nearby surfaces are covered before any work starts. Most visits take a couple of hours, and the room is left clean and tidy.
- First we strip out every bit of the old mastic.
- We clean the joint and treat any mould.
- We ensure the joint is completely dry.
- For a bath, we fill it with water first so the joint is at its widest.
- New mould-resistant silicone goes on and is tooled to a neat finish, including around the taps.
How to prepare
- Let the surface dry out before the visit
- Let us know which floor the room is on
- Clear toiletries, mats and anything else from around the area
How to get a price
We price from pictures so you do not have to wait in for a survey. Use the quote form, or ring 0345 017 0787 to talk it through.
