Rob and Tony arrived at the indicated time and carried out what was a difficult job. The end job was carried out in a very professional and excellent manner. Neither of them could do enough to help. I will be using them again in the future and highly recommend this company to anyone looking for the right trade person. Well please with the result.

GHS Landscapes

Cellar & Basement Conversion in Wallingford

We are a local Construction Company with a background in commercial building & groundworks. We are used to working to high specifications with minimal tolerances. Leaving you with a high end look with a beauty that is more than skin deep, its durable too! Its Important that a house has a solid foundation, but not just houses. Every aspect of construction is only as strong as it weakest link so we don't just concentrate on leaving a nice finish. You want that look to endure so we don't cut corners behind the scenes. Everything we do is constructed in accordance with industry standards norms. So our extensions get nice deep footings, So do garden walls. Our driveways are always excavated to the right depth, and the sub base constructed in graded road stone, not cheaper sub base materials because they are not as good. We never use a nail where a bolt or screw will do better, because it lasts longer that way! With 30 years in the trade behind me we have the experience, knowledge, and contacts to get you the best materials and reasonable prices. So whilst quality work has a cost to it, it need not be exorbitant, nor out of your reach! With us you are sure of the right advice, at a reasonable price.

I am extremely pleased with GHS who recently renovated our patio. The existing concrete slabs had sunk in many places, producing an uneven surface that ponded when it rained and caused a trip hazard. GHS lifted the slabs, compacted the underlay and relaid the slabs on a new mortar base, giving us a smooth patio without trip hazards which now drains effectively. GHS carried out the work quickly and efficiently and were extremely friendly, polite and helpful. I highly recommend them.

Unfortunately this job seemed to be beyond Jay's ability and we had to stop it part way through and find someone else to finish it. On the positive side Jay recognised this and was very apologetic and was certainly not trying to rip us off. But I cannot recommend him for this type of job (replacing existing front door and frame with new frame and door).

Rob and his team did a really high quality job and we are very pleased with the end result (and I am the son of a builder, so my expectations were high to start with).. The finish is excellent on the render and the quality is constant through what was a fairly large rendering job on my detached house. The team were tidy and worked hard to the deadline throughout the process. If you need a high quality rendering job, then I would highly recommending considering Rob's services.

George responded quickly to my request, gave a very reasonable quote, did a really quite tricky and complicated job above a conservatory, to fix cracks in the pebbledash of an external wall, and seal all around the windows. A fortnight later he re-plastered internally. George gives the impression of being somewhat chaotic! But he is extremely experienced, knows what he is doing, and actually did a very good job. The timings and quote agreed to were respected, he was polite and cordial, and communicated well

Sadly as much as the extension looks fine on the outside, there have been too many issues behind the scenes that we have had to get remedied, which has been a huge additional ongoing cost to us. The team are not experts and will not do a thorough job. We have recently had to deal with a big health and safety electrical issue due to their inability to do things properly.
