Installation and maintenance

The base for your greenhouse is very important for prolonging the life of your building.

Movement in the foundations can cause warping of the frame which can lead to glass breakages as well as improper door and roof vent function.

We can provide a small base service, or can put you in touch with reputable builders for larger base work.


Base Preparataion

The base of your greenhouse is very important and can affect the longevity of your greenhouse. There a many types of base but 4 common options are listed below:

- Flat, level and compacted soil. We would  recommend a     greenhouse size of no more than 8x10ft  for a base of this     nature. Above this size, frame weight becomes a concern.     Cost outlay is fairly low for this type of base.

- Perimeter or full paving slab base. This type of base is       cost effective for solid foundations and suitable for most

   sizes. Using a full bed wet mix of sand cement mortar to

   ensure the area stays flat and level for years to come.

- Railway sleeper perimeter base. Using railway sleepers

   provides a very cost effective perimeter base for the

   greenhouse frame to sit on. 

- Full concrete pad base. Solid foundation suitable for all

   sizes of greenhouse. More expensive then a slab base, but

   will last for a longer period of time.

We are happy to give advice and help on what style and size base you would need. We can prepare a soil base for your greenhouse during the installation stages at an extra cost.  Railway sleeper, paving slab and concrete bases for greenhouses can be carried out by us within 20 miles of the Bristol area.

Approximate prices:

-£8 per square foot for a paving slab base

-£9 per square foot for a concrete base

Guideline pricing is available on asking, and if you are based further than our usual working radius, we may still be able to help.
