VERY BAD

AVOID THEM, you will only loose your money and will have to pay for someone else to do the waterproofing work again. Andrew Blake is an excellent salesman but his speech is totally empty of meaning, his company doesn’t provide any reliable services and when you start realizing that, he will no more respond to mail/whatsapp/ phone calls and drag works beyond acceptable and finally never finish them. And the worst of all, craftsmanship is so bad that on our roof it started leaking before works were finished. AVOID THEM!
