As one of the top window contractors in Singapore, Pang Giap has received a lot of praise from their clients. Take a look at some of them:

“Engaging Pang Giap to replace my windows is by far one of the best things that has happened to me. If you’ve dealt with contractors before, you would know what I mean. To begin with, the surveyor, Mr. Ang who came to my house to quote, unlike other contractors, took measurements right to the millimeters without any indication that he will be given the job. His suggestion and recommendations were honest and sincere. Contrary to all other contractors who wanted me to change the entire kitchen windows because a faulty grille, Mr. Ang offers to repair it instead of replacing, thus saving cost.”

“Pang giap has an experienced team with good knowledge which give sincere advice.  The team is very careful and detailed throughout the process installing the windows and grilles. Reasonable price. Appreciate your hard work.  Thank you.”

“I am also satisfied with Pang Giap’s service from sales to installation. Slim grill is so useful for hanging laundry during the day too. It’s a little costly compared to other type/traditional wrought iron but slim grill will never go out of fashion and I would definitely recommend you to get slim grill for your home too!”
