Our building services in Milton Keynes
Mason Property Services Ltd has been building, extending, converting and maintaining homes across Milton Keynes for more than 30 years. From the modern grid roads of Central Milton Keynes to the older villages of Newport Pagnell, Olney and Stony Stratford, we have probably worked within a mile of your home — and the chances are one of your neighbours can vouch for us.
As FENSA-registered installers and Checkatrade members carrying £10 million of public and employers liability insurance, we sit at the well-insured, well-accredited end of the Milton Keynes building trade. We do not run a sales team and we do not pay commission to introducers — every job comes from repeat business or personal recommendation. That is why we can keep the prices fair and the relationship straightforward.

Builders in Milton Keynes — Frequently Asked Questions
Each question should be a visible H3 with the body answer beneath, AND wrapped in the FAQ Schema markup shown earlier.
How much do builders cost in Milton Keynes?
Builder day rates in Milton Keynes typically range from £180 to £260 per day for a single tradesperson. A single-storey kitchen extension usually costs £30,000–£55,000 including all trades. A loft conversion costs £45,000–£85,000 depending on whether dormers are added. Mason Property Services provides a free written fixed-price quote after a site visit so you know the total cost up front.
Do you cover the whole of Milton Keynes?
Yes. We work across every MK postcode including MK1 to MK19, and the surrounding towns of Newport Pagnell, Bletchley, Wolverton, Stony Stratford, Olney, Buckingham, Towcester and Aylesbury.
Are you FENSA registered?
Yes. Mason Property Services Ltd is a long-standing FENSA member, which means we are competent to install double glazing to building regulations and you do not need separate council approval for replacement windows we fit.
How much insurance do you carry?
We carry £10 million of Public and Employers Liability insurance — substantially more than the £1m–£2m minimum most domestic builders carry. This protects you, your property and our team on every job.
How long have you been trading?
Mason Property Services Ltd has been providing building and home improvement services in Milton Keynes and Buckinghamshire for over 30 years. Much of our work today comes from repeat customers and personal recommendation.
What do you not do?
We do not undertake structural engineering work or Gas Safe boiler installations in-house — we use trusted sub-contractors for those. We do not do roofing repairs on a one-off basis (though we re-roof as part of a larger build). For everything else from a single garage door to a full house build, we are happy to quote.
Do you provide free quotes?
Yes. We visit your property, discuss what you want, then email a free written fixed-price quote within a week. There is no deposit required and no obligation to proceed.
Do you work weekends?
Yes — we operate seven days a week. Weekend work is usually finishing or remedial; major structural and noisy work is carried out Monday to Friday to respect neighbours.
