What customers said about this work
What a find!!!! They do exist..... A workman that turns up when he says he will, works non stop and tidies up as he goes along. Anthony has done a great job and takes pride in his work. I would definitely recommend him
MyBuilderWe would definitely recommend this company. We had our bedroom plastered and the job was done to a really high standard. The job was completed quickly and efficiently.
Anthony did a fantastic job. 3 rooms including ceilings needed boarding and skimming. On time every day, really quick and high quality work and definitely going to use again.
MyBuilderHouse Extensions
What house extensions cover
An extension is judged on whether it looks like it has always been there or looks stuck on, and the finish decides that more than the shape does. Rendering the new work, often wrapping onto the original house so there is no visible seam, is the single most effective way to tie the two together.
Inside, it is the same story in reverse: boarded, taped and skimmed so that the new room and the old one meet without a step, a shadow line or a change of texture where the wall was opened up.

Frequently asked questions
Questions people ask about house extensions
If the answer you want is not here, ring and ask.
How soon can a new extension be rendered?
New masonry needs to dry out first, typically several weeks, and longer through winter. Rendering too early risks efflorescence and shrinkage cracks as the wall dries behind the finish. We will give you an honest window based on when the blockwork went up and the weather since.
Can you render just the extension, not the whole house?
Yes, and it is common. Be aware the new render will not weather-match an older rendered elevation exactly. Where a seamless look matters, rendering the full elevation up to a natural break gives a far better result and we will price both.
Do you build extensions as well?
No. We are plasterers and renderers. We finish extensions inside and out and work alongside builders regularly, but the structural build itself is not our trade and we will not pretend otherwise.
Will the join between new and old show?
Not if it is detailed properly. The junction is treated as a movement joint rather than rendered straight across, because the two structures will always move slightly differently. Rendering over it rigidly is what produces the crack you see on so many extensions.
Should I skim the original room as well as the extension?
In a knock-through, usually yes. A brand new skimmed wall next to a forty-year-old one shows the difference in flatness and texture immediately, especially under downlights. It costs more up front and it is what makes the finished space read as one room.
Can you match the render colour on the existing house?
We can get close, and where the original is silicone or monocouche the match can be very good. On old painted render it is harder, because the existing colour has faded unevenly. We will show you the options honestly rather than promise an exact match.
We do this across the area: Liverpool and Southport, and everywhere else we work.

About house extensions in Southport
Rendering new work into old
The junction between an extension and the original house is where movement happens, because two structures of different ages and foundations never settle identically. That junction is treated as a movement joint rather than rendered straight over and hoped for.
Where the whole elevation is being rendered, the extension and the original disappear into one surface and the result is seamless. Where only the new work is rendered, we will be honest at estimate stage about how visible the transition will be.
New masonry needs time
New blockwork and brickwork hold a lot of construction moisture, and it has to get out before a render system goes over it. Render onto masonry that is still wet and you risk staining, efflorescence salting through the finish, and shrinkage cracking as the wall dries behind it.
How long depends on the season and the build. We would rather give you a realistic window than turn up early, get it on quickly and leave you with a wall that blooms white in six months.
Inside: making two rooms into one
Where a wall has been opened up and a steel installed, the new opening gets boarded and boxed so the beam disappears cleanly and the reveals line through with the existing walls. Getting the new plaster flush with the old is where most of the skill goes.
In an open-plan knock-through it is usually worth skimming the original room as well as the new one. Old walls and a brand new surface rarely match closely enough, and the difference is obvious under a run of downlights.
