I was thinking about doing it myself but am really glad I didn't because they did a much better job than I would have. That said, they were a little pricey as they said I had to pay the minimum they charge for a trip out. Then again, the other company I called wouldn't even come out and advised me on how to fix the problem myself. Their solution (to address the crack only from the outside...it ran through the wall) would not have been nearly as thorough as what Allmaster did (drilled several holes a long the crack and injected, I believe, a polyurethane sealant to seal the crack from the inside). I'm happy with the work and you get what you pay for. I would hire them again. They were prompt in coming out, punctual, sent a written estimate by email the day I called (even for a small job), cleaned up and took the time to look at some other areas of concern. In short, they are a good company and do a professional job...the kind you want to hire. The person who came out was very knowledgeable, helpful and friendly. **★★★★★ — tomjammon, July 2014** > First off let me tell you I had 3 other window contractors come out to my home with similar low balling ploys. They would have a ridiculously low priced ad and once they get there they starting having all these ad ons to jack up the price. These guys DID NOT do that. It was a great experience from start to finish. I truly appreciated not having to play a game. They came in an explained the difference between the couple models they offered. They had a good window and a better one with the two panes and low e which is what we wanted from the beginning. They measured everything and we got our price. Once the windows were delivered they called and put us on their install schedule with a date that worked for both of us. The installation went fabulous. There were no hiccups and the installers were incredibly nice and professional. I highly recommend Allmaster. We will definitely be using them for our upcoming siding project next year!!! **★★★★★ — Billy Garver, April 2014** > Had my siding and Trim replaced! They did a excellent job! Quality work in a timely fashion! Would recommend to all ! Thank You! Very happy and would consider for more of my home projects! AAAAAA++++++++ **★★★★★ — centerjc, April 2014** > I’m quite happy with the improvement in energy efficiency that was achieved by installing the radiant barrier in my attic last year. Even after installing a new energy efficient heating/AC system the previous year, the AC bill was much lower than it was the year before(barrier) and my heating bill this last, long cold snowy winter was lower than it’s ever been in the thirty years I’ve lived here! > Great job guys! **★★★★★ — Felicia Price, April 2014** > Team did a great job and we would give our highest recommendation. Took time during the estimate and all through the actual project work to explain what was needed and being done. Angel and his crew are friendly, courteous, and professional. **★★★★★ — tlkilmer, April 2014** > I have had multiple projects done on my house in preparation for selling. Allmaster builders did an excellent job and were very affordable. I definitely recommend their services to anyone looking for a good general contractor. ## Selected projects - [Outdoor Living Featuring Belgard Products](https://www.houzz.com/hznb/projects/outdoor-living-featuring-belgard-products-pj-vj~3138650) - Location: Not specified - Photos: 30 - [6- Tiered Keystone Retaining Wall](https://www.houzz.com/hznb/projects/6-tiered-keystone-retaining-wall-pj-vj~493897) - Location: Parkville, MD - Photos: 19 - [tiered retaining wall around pool](https://www.houzz.com/hznb/projects/tiered-retaining-wall-around-pool-pj-vj~6857718) - Location: Not specified - Photos: 7 - [More outdoor living](https://www.houzz.com/hznb/projects/more-outdoor-living-pj-vj~6857709) - Location: Not specified - Photos: 26 - [2 - Tiered Belgard Century Wall](https://www.houzz.com/hznb/projects/2-tiered-belgard-century-wall-pj-vj~3140316) - Location: Cheverly, MD - Photos: 8 - [Keystone Driveway Retaining Wall](https://www.houzz.com/hznb/projects/keystone-driveway-retaining-wall-pj-vj~3140310) - Location: Towson, MD - Photos: 6 - [Belgard Bench and fire pit](https://www.houzz.com/hznb/projects/belgard-bench-and-fire-pit-pj-vj~5636383) - Location: Columbia, MD - Photos: 24 - [Belgard Keystone wall with Vinyl Railing](https://www.houzz.com/hznb/projects/belgard-keystone-wall-with-vinyl-railing-pj-vj~3140327) - Location: Laurel, MD - Photos: 12 - [Natural Stone Retaining Wall & Patio](https://www.houzz.com/hznb/projects/natural-stone-retaining-wall-and-patio-pj-vj~3140280) - Location: Parkville, MD - Photos: 16 [See all 9 projects](https://www.houzz.com/professionals/general-contractors/allmaster-builders-inc-pfvwus-pf~1225596535) ## Ideabooks - [Wish List](https://www.houzz.com/ideabooks/128821643/list/wish-list) — 2 ideas [See all 1 ideabook](https://www.houzz.com/ideabooks/users/allmaster7918) ## Community Q&A **Q: Ann** *(in Photo Questions)* I love the accent tile.
