The lady actually took a razor blade to it and destroyed it. A RAZOR BLADE! (See photos) I should have known when I walked into that sty that is was a mistake. The place is filthy, there is crap everywhere and probably the most unprofessional tailoring shop I have ever been in. So now I have to either find a new dress to get married in in 3 weeks or pay a small fortune to get it repaired somehow. Read the other reviews. These folks are a total disaster.

They gave me the scrap that they cut off and it was uneven. Just beware as I asked them for a price before dropping off and they said they "didn't know but I must pay in cash". This should have been my first clue because once they're done, they can charge you what ever they feel like. Ridiculous

John Valher Alterations is just perfect…read more Many places offer alterations. Some are in addition to other services - cleaners, bridal dresses, etc. From my experience John Valher Alterations focuses on fixing and creating clothes. The majority of my clothes are custom tailored for me. Shirts, pants, jackets. Jeans are not one of those items and typically they need to be adjusted for fit. For a long time, I have been searching for someone who can do a quality job, in a timely manner, and done so at a fair price. John Valher Alterations is now my go to spot. I picked up four pairs of jeans yesterday and dropped off nine more pairs yesterday. From the moment I reached out (via Yelp), throughout the first measuring, and then scheduling pickup, the process was fast and easy. The shop is somewhat nondescript but it is setup to do what needs doing - altering clothing. Highly recommend visiting John Valher Alterations for your tailoring needs.

I have been in and out of this place for years. The service had always been slow and most of the…read moretime they were unable to fix what we needed done. I found a really great family owned place that had been in Boulder for two generations and I used them for years. When rents in Boulder got too high, they moved to Nederland. I recently heard that they finally closed forever about a year ago which left me in a quandary about where to get my husband's favorite belt repaired. It is nearly 20 years old and the leather quality sound but the stitching that holds the buckle and loop on had completely torn away. We went in on Friday to see if the staff here could fix it. They said they could and it would be ready on Monday. We paid in advance about what the belt originally cost but hand labor is not cheap these days. Amazingly, they called today to tell us it was ready. We went over to the shop and indeed it looked very good. At least now we can put off the search for a new perfect belt, hopefully for another decade. Note: the place is still a mess inside and there are still dissatisfied customers in the line ahead and behind you. Hopefully your project will turn out as well as ours did.

Is this a particularly busy season for shoe repair (Fall, 2026)? When I call the store to inquire, they say "we will give you a call when it's ready". If I had known how long it would take, I might have just "toughed-it-out" and continued to wear the boots!
