The team first gave a competative quote for the work. A good start! They turned up on time, and then paid attention to my requirements before starting the job. They worked hard and efficiently together to get the job done. 7:30 AM to 18:00 without a break. The result was to professional standards. Would I recommend them? Yes, very much so! In fact I'm already planning to get them back to do another project for me. I think that statement really says it all.

GHS Landscapes

Cellar & Basement Conversion in Alton

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.

Shortly after finishing our renovation the floor began to lift, after a 2-year battle and almost court they admitted it was a fitting fault. Not ideal for a 12k job. Now our sink has fallen in, turns out he has used the world's smallest bit of wood and some sealant to fix it to the underside of our granite worktops rather than correctly fitting it using the fixings on the actual sink. Add to this, gaps between drawers and misaligned cupboards and you get the idea.

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
