Keystone Siding Corp     

Keystone Siding installed siding on our home 13 years and we’ve been very happy with it. No problems at all so it was an easy choice to elect Keystone for our replacement windows.  The price was right so we decided to replace all of our windows.  We look forward to spending less on heat with the triple pane windows, and they will be an attractive selling point when it comes time to sell our home.

I’m delighted with the Keystone triple pane windows installed two weeks ago.  We’ve just recorded some of the coldest temperatures ever recorded inNew Hampshireand yet I’ve found myself in the luxurious position  of actually turning down my thermostat.  I will recommend your company to anyone who is thinking of vastly improving the efficiency of preserving heat in their home.

As you know we previously dealt with many other replacement window companies before we met you. I didn’t like their high pressure sales tactics.  You gave us your best price on your first quote which was fair and far lower than your competitors. You can not appreciate how refreshing this was to us!  18 windows were replaced on a very cold day in December in 1 day.  We’ve noticed the new windows are keeping our house warmer and that our oil furnace doesn’t start as often, saving expensive fuel.

I would like to express my happiness and 110% satisfaction on the job you did for us. I can’t believe what a difference the new siding and windows make! It was an absolute pleasure to work with you and have already recommended you to some of my colleagues.

When we decided to put vinyl siding on our home we did our homework. From all the companies that gave us estimates, Keystone was by far the best choice.   We would highly recommend your company to anyone interested in having a professional job done at a reasonable price.

The most honest company I have seen in a long time.  Our home is beautiful.  Everyone that has seen it also tells us this.

What a difference it has made to the appearance of the house and property.  To think of all the time and work involved over the years of painting just to keep up the outside appearance makes me wonder what we were thinking.  The benefits far outweigh the costs.

We recently had 16 Keystone windows replaced in our home.  The difference has been remarkable. The house has been noticeably warmer and street noise has been significantly reduced.        B.M.  Rollinsford

Our home has undergone a transformation during the past week which can only be described as wonderful.  After your company’s expert installation of vinyl siding, our house looks and feels brand new.

The quality of the windows and installation were great, as was the detailed work on the trim.

I just wanted to take a minute to let you know how happy we are with our new Keystone windows.  I felt “no pressure” from anyone and it made doing business much easier.  When it comes to replacing the siding, you’ll be the person I call.

J.W. Derry 

There are no drafts near any of the windows! The house is nice and warm.  We were quite impressed with the way the project was managed and the expediency with which it was completed.

C.B.  Merrimack 

Your suggestions for enhancing our home were well though out and clearly stated.  We found you to be reasonably priced and not pushy, and we felt that to be very considerate on your part.

L.C.   Rochester  

The siding was installed very professionally by your fine men.  They are the best in the business as far as we’re concerned.  The price was reasonable and everything was done exactly as promised.

H.H.  North Woodstock 

Our house looks so nice and we are both so happy with the siding. We have had a lot of compliments on how nice it looks.

J.H.      Madison 

Our family is very pleased with how our home turned out. It changed from drab, peeling, hard to paint house, to one of low maintenance and beauty in just a little over a week.

K.C.  Keene  

We couldn’t be happier with our decision to hire Keystone to complete this job.

J.C. Dover

We are very delighted with the work done on our home.  …very professional and attention to detail. You can be sure we will highly recommend Keystone Siding Corp.

J.L.  Charlestown

It didn’t think it was possible, but our Keystone triple paned widows cut our energy bill well over half!  Amazing!

N.M.  Claremont

I would like you to know that we are very pleased with the windows we purchased from Keystone.  They were installed in just over 3 weeks from when we ordered them! I received quality windows at a good price, installed by capable craftsmen, from a company which I was happy to do business with.

M.F  Nashua

The most important aspect of the new windows is the elimination of the cool drafts we experienced in past winters.  Thanks for a job well done.

J.M. Nashua

We would recommend you company to everyone.  We have never been this satisfied with anyone else in the past.

R.J. Derry

Our heating costs will be greatly reduced from the purchase of our new windows.  Again. We would like to thank Keystone for a great job.

R.K.  Tilton

I would like to express our deepest thanks for our 21 new Keystone windows last year.  We saved over 50% on our fuel bill.  It was the best money we ever spent.

C.K. Bristol

We are absolutely delighted with the new siding and windows installed by your company.  We chose Keystone over several other companies due to your quality, price, and a blemish free record with the Better Business Bureau.

K.D. Londonderry

Even though we have had only a few cold nights, we can feel the difference.  With the price of oil, we are glad we did this at this time.

J.P.  Londonderry

Several neighbors have stopped to make comments on how good the house looks and how amazed at how quickly the installation was completed.

A.N.  Springfield

Thanks for the fabulous job! The vinyl siding and the new windows look absolutely wonderful.  I would recommend you to anyone.

S.M.   Amherst

I can’t tell you with how pleased I am with the installation of my new siding.  From start to finish this experience has been nothing but positive.
