What Our Customers Say

Sam Upton

Burras LTD

We used Southern Liquid Screeds to screed the property as they came highly recommended. They provided a very professional service and were very accommodating to our timescale. They only took a few hours to install around 200m2 of screed and left a brilliant finish. We would defiantly use them again.

I would like to echo the comments of earlier posts. Pat and his team are great guys to deal with. Very professional, very friendly and competitive on price. 175m2 of screed laid in less than half a day with absolutely no issues. I wouldn’t hesitate to recommend them. 

Peter Kayworth

Home Owner, Soberton, Hampshire 

We had a difficult oak- framed extension project, we needed UFH and Screed to three different levels.  
Other solutions were a) expensive b) increased step height and c) involved a pre-level screed delaying the project. 
After discussing with SLS, they did the whole 40m2 job, designed and installed UFH with Anhydrite Screed, all done a day and half!  
The screed has been down 3 months with no cracking evident. A straight forward job with an efficient team that provide excellent support throughout. 
Very pleased.

M.A. Irwin

Peter, I have already recommended your company…  
Zak and the boys were very easy to deal with, very knowledgeable about the product and helpful with their advice as to what we needed to do, before and after the screed was laid. I believe this is definitely the way to go with screeding in the future, and I would not hesitate to use your company again.
All the best, Mark

Barry Marks

Home Owner, Fareham, Hampshire

I used SLS for a Garage/playroom floor 30m2. The upfront support with the pricing and the many, many questions I asked was quite frankly awesome. Installation day came and they found a problem with the base and helped me rectify it as part of the site survey. Floor was poured and done within a few hours.
I had a few questions in the days that followed installation which the team helped me without groaning!
So the process was done and my favorite part came, out came the level……. my garage now has the most level floor of my whole house!

Anand Kothari

Trout Rise Developments

Fantastic service provided by Pat and his team. We normally use traditional screeds on our projects but due to depth constraints we had to diversify and opted for a liquid screed solution. SLS were extremely helpful in guiding us through the process and went above and beyond what they were originally paid to do. The finish is excellent. Furthermore the prices were far more competitive than any in the local area. I would highly recommend this company to anyone considering liquid for their project.
