For a start, in my opinion the Consumer Code for Home Builders is as much use as a chocolate teapot.
I would bet my house on it they would only award you £500 IF you can prove written evidence required) what you are claiming for. Furthermore any problems with quality and defects are NOT covered at all by the CCHB! The CCHB is funded to a large part by the NHBC too!
1. Bricks should match. The best you can hope for is a tinting specialist (Brick Doctor) who would paint tint the brick the blend them in to make it less obvious. Perhaps post a photo on here and Twitter and Facebook might shame them into rebuilding but I doubt it.
2. Weak mortar is a serious issue. One that if addressed would mean the brickwork could be replaced at the same time. However plc housebuilders and the NHBC are past masters at denying claims on this. It would take several years to get anywhere and lots of independent mortar testing, which even then the NHBC "expert" would dismiss out of hand. See more on
weak mortar in my three blog articles .
3. It is a breach of NHBC standards to have any builders rubble and obstructions in the ground. As you have contaminated ground with asbestos write to the NHBC and the council as this is an environmental hazard. be aware the council may require you to clear the contaminants as the property owner.
4. Creaking ceilings and floor well covered on this forum. Use the search function. Screwing the ceilings and floors won't be a solution.
5. Pipes are likely to be plastic these days and held with plastic clips. Obviously they expand and contract causing the clicking. They should be wrapped with hair felt.
6. The boiler should not be making any load noises. If left, it could end up with the boiler breaking down altogether just when you need it the most. It could also be dangerous as it is likely to not have been installed correctly.
This needs someone to look at it next week!
