Ashburn, VA Window and Glazing Professionals

The importance of the right windows to the appearance of your home can’t be overlooked; their arrangement giving symmetry and character to a building. And of course they also perform valuable functions such as letting light into the home and ventilation. But if your home still retains its original period sash windows, and you don’t have double glazing or secondary glazing, your windows can also make for noisy days, chilly evenings and sizeable energy bills. So, when you do want to upgrade or replace your windows, which way do you turn? Experienced Ashburn, VA window companies and glaziers will be able to advise you when to restore or repair your windows, and when to replace. If it is to be the latter, your replacement windows will be intended to last, so it’s not a decision that should be taken lightly. You want to make the right choice for your new windows, whether you opt for replacement sash, uPVC windows or a double glazed windows upgrade. So be sure to choose the right Ashburn, VA window companies and window manufacturers and you’ll sleep better at night, not least because you will be protecting your investment for years to come. More

Windows on Washington Ltd
Glaziers and Window Specialists in Ashburn, VA
"Description Of Work: We contracted Windows on Washington to perform three upgrades to our home: 1) Replace entry door -- upgrading the original double (french) entry door with a single ProVia door with sidelights 2) Replace all windows -- 16 (original) windows were replaced with Okna 800 series windows including a complete tear-out of an existing bay window 3) Insulation and Air Sealing -- Attic insulation, air sealing, and insulation in the cantilevers in our split level home Comments: The work being reviewed is the first major renovation project we began since buying our (1967-built) home in mid 2011. Upon reflection of our experience with WoW, there are five main areas that are important to consider when working with a contractor and WoW excelled on all of these dimensions. Before getting into the details, I will say that overall, our home is more efficient, our home is quieter, and our windows and door are beautiful! And we are more knowledgeable about what we can do to continue to improve our home's energy efficiency. We will be using WoW for upcoming projects for a new roof and siding -- without question. 1) Research & Quote Process: WoW excelled in this area. To put it lightly, our research process is extensive. We started the research process, both for materials and contractors in late 2011 and finally committed to a project in late February 2012. WoW really excelled in this area -- we first met with Kevin (sales) and had a great first impression. He was very knowledgable and helpful, but not at all 'pushy' -- he let the quality of materials, reviews, etc speak for themselves and stopped at nothing to answer questions for us. He didn't show up with fancy heat lamps, or with a lovely color palette. He showed up wanting to understand what we wanted and to educate us on our options. We visited WoW's showroom and met the same helpfulness in their office. As our research process progressed, Kevin brought in Eric (the owner of the company) and another home visit was made by them - not to sell, but to answer our questions, evaluate the project, and give us advice. Not only did Eric, Kevin, and the team give us sound advice about the project at hand, but they gave us advice about projects they weren't selling us directly -- just honest, good advice for new homeowners. 2) Pricing: WoW's prices were competitive. They aren't the most expensive, but they also aren't the cheapest. That is for two reasons: a) They only install high quality materials -- they won't be your $200/window company because they want your windows to be efficient and to hold up to the test of time. b) They pay attention to the installation process and the materials they use down to the caulk used on the windows. What good is a nice window if water or air leaks in around the edges after a couple of years? With all that said, the prices are still competitive and I think it would be hard to find a better combination of price and quality. 3) Knowledge about the industry, installation, etc: Exceptional! As part of my research process, I read as much as I could in trade magazines, websites, etc about windows, doors, and insulation. I knew I wanted to stick with a few specific brands of doors and windows that were high quality and efficient and that helped narrow my search for contractors. As I searched forums on home construction, window reviews, etc I found that WoW is very active on these forums. At first this gave me a pause because I worried they may be on these forums to self-promote. But I can assure you that is not at all the case. WoW is on these forums because they are passionate about this industry of home efficiency, insulation, windows, doors, roofing, etc. I have probably read dozens of posts by WoW on these forums and never found one that was self promoting -- all of them are about sharing knowledge about materials, installation advice, simple DIY advice, etc. This is a huge positive for the integrity and credibility of the company -- and also the passion for the work. I am pretty passionate about DIY jobs -- partly because "if it's worth doing, it's worth doing right -- the first time". I found WoW to share this same perspective and it gave me a great deal of confidence in their approach to the work. 4) Materials Available/Used: Only the best! WoW only carries some of the best materials you can use in the industry. If you search the internet for high quality windows -- you should find Okna to be at or near the top. If you search for high quality doors -- you should find ProVia to be at or near the top. They do have other options and will quote pretty much anything they feel is worth installing. They don't push one specific thing, but plainly lay out the pros and cons for the homeowner to consider. 5) Installation/workmanship: Top Notch! I cannot say enough about the professionalism and fortitude WoW had. The easy stuff first -- Our windows were installed quickly -- in a day. Our insulation was installed quickly, in less than a day. After a few months, there are no issues -- zero. Now for the tricky part... we wanted our double entry door replaced with a single door with sidelights. When WoW was out for final measurements, they felt it may be tight to fit the door and sidelights we wanted -- this was complicated by the fact that we have brick surrounding the entry door -- not an easy job to squeeze an extra half-inch into the opening without masonry work. After some research on their end, they felt it wouldn't work, but said they felt a company they work with from time to time could 'custom make' the door we wanted from ProVia and trim the sidelights down every so slightly so it would fit. Before committing to this other company, they asked this company for a sample of the product. After receiving it, they felt it wasn't satisfactory -- it didn't look as good as the ProVia and thus they wouldn't sell it to us. WoW didn't give up -- they came back to our house and took more measurements and found a way to make it work -- or at least they thought. On the day of the door install, after removing our existing door, they found that some of the brick that wasn't exposed stuck out further than they thought... making the door opening slightly too small for the door they had sitting on their truck. Well, WoW didn't give up... they broke out the chisels and drills and began some basic masonry work to chisel back the brick (non-exposed) so the door would fit. Eric was on the job site at this time -- he wanted to make sure this was done right. WoW finished the door install -- and it looked great! Aside from a little red brick dust as evidence of the tough work, the whole project was done on time and no additional charge to us -- even though it was clearly an unexpected obstacle. Finally -- I feel like it's hard to find a company who cares as much about your house as you do. But I have to say that I think WoW just might be that company."

Hodges Windows & Doors
Glaziers and Window Specialists in Ashburn, VA
"We have used Hodges on several different projects- window replacements in 3 different properties, as well as door replacement. Their sales staff is knowledgeable about their products, they are prompt with installation, and they follow up with any problems. They don't do any painting, so plan on either painting trim yourself, or hiring a painter after the job is done. we have recommended them to several other people, who have been equally satisfied."

Shenandoah Sash & Door
Glaziers and Window Specialists in Ashburn, VA
"I am in the planning stages of a major remodel which includes replacing many windows. From my first call to Shenandoah Sash & Door until my most recent communications with them, they have been nothing but wonderful. I visited their showroom and was greeted by Tom Sanders the General Manager, who gave me a tour and thoroughly explained all Kolbe's latest products. After my visit he was quick to respond to my emails and answer any questions that I had. I am new to the area and he was kind enough to connect me with local vendors that I asked about. I will definitely be using this company when I order windows."

Nova Exteriors
Glaziers and Window Specialists in Ashburn, VA
"We asked Nova Exteriors to come to our home to give us a free estimate on a new front door. They sell and install the top-notch ProVia line of doors. We were so impressed with their sales pitch and line of products, we also decided to have Nova Exteriors replace the worn out shutters on our home as well. We did not pay a penny more than the estimate that was provided, the work was completed in an exceptionally timely and professional manner, and I would not hesitate to recommend Nova Exteriors to others or to use them again for other home projects."

Paul Henry's Window Installation, Inc.
Glaziers and Window Specialists in Ashburn, VA
"They are a locally owned business, and we felt like he was more straightforward than the other larger companies out there. Also, the prices were reasonable for the type of window that we purchased, which was one of his top of the line models. His crews were professional, efficient and more than happy to clean up after their work. We bought a third of the windows last year, the 2nd third this year. There was no comparison as far as the pricing was concerned. I was quoted about $10,000 higher with another company - and even with their promotion, there was still no comparison to Paul Henry’s prices."

Window Universe
Glaziers and Window Specialists in Ashburn, VA
"From the sales rep to the installers, Window Universe was very professional. The sales rep was knowledgeable, detailed and very easy-going. I appreciated that he did not present with a pushy sales-pitch. The process thereafter played out exactly how the sales rep said it would. I received a call for a rep to come out and measure, then my windows were ordered, upon receipt, I was called to set up an install appointment. The installers worked on time, worked very hard and completed a very large job in just one day. Overall, I was very pleased with my experience with Windows Universe."

What can specialist window companies, glaziers or window fitters in Ashburn, VA do for me?


Specialist Ashburn, VA window companies and fitters can diagnose problems and prescribe a choice of remedies, while keeping in mind factors such as the style of your property, ease of operation, budget, noise reduction, thermal efficiency (the lower the U-value, the better), durability and maintenance.

What type of window company should I hire?


Like most professions, window companies and fitters often have specialisms. The Ashburn, VA glaziers you choose should reflect the types of new and replacement windows you are seeking, for example:

  • A period window specialist will have particular expertise in how to deal with period windows. For example, you may be living in a Georgian property with original sash windows that have seen better days. They need draught proofing, the window frames are showing signs of rot, the sash mechanisms aren’t working smoothly and the budget is tight. A sash window refurbishment specialist, together with his team of glaziers and joiners, can reinvigorate your period windows, help install secondary glazing, or provide authentic replacement windows.
